Brief Update Post - And Some Exciting News!!

Just a very brief update post.

First, I'd like to take this opportunity to advise my Readers, that the recent reviews of Titley Scientific's detectors will be updated soon: I will be adding a bit more information, screenshots, and expanded summaries for each.
I'm also in the process of testing microphones from Titley (for use on their unattended recording devices).


And finally, after many years of showing interest in reviewing a certain bat detector, I've just been informed: it is en route!
I'm going to have an opportunity to review a bat detector which I've been admiring for years!
I won't reveal the make or model of the bat detector at this moment (soon!). But I'm just excited to share the news!


I just printed-out the (draft version) of the User Manual - And I'm very impressed, just from skimming through it!

Happy bat detecting!

Review: The AnaBat Scout From Titley Scientific Part 2 of 2

Review: The AnaBat Scout From Titley Scientific Part 2 of 2

Let's begin with a quick summary, or overview of The AnaBat Scout - some of my first impressions:
As can be seen in the preceding posts (in Part 1 of this review, etc.) the AnaBat Scout arrives very well packaged and protected. I like the overall aesthetic of this unit; I can see that they have molded The AnaBat Scout into an ergonomic design. It is lightweight (with batteries installed), and it feels natural and comfortable in the hand.


A short video, demonstrating powering on The AnaBat Scout (with display set to Low brightness).

Amoung some of The Scout's features, are:
  •  The ability to record voice notes (as previously mentioned, the Mic for this is located above the display screen).
  •  Glow-in-the-dark buttons. In practice, I found that the buttons were not easy to "charge" (expose to a fairly bright light source). And not at all easy to see in the dark (out in the field, etc.).*
  •  It includes a protective case and lanyard.
*I couldn't help but to immediately think that Tritium would've been very effective, instead of the material currently used for the buttons. Although I have a feeling, that some Ecologists might object to it's use...

The built-in Bat Counter of The Anabat Scout will be a welcomed feature for Ecologists / Bat Workers performing emergence surveys, etc. It will record the date, time, and location with each button press, into a .csv file (commonly read with Microsoft Excel). By default, the increment (each In or Out button push) is 1, but may be increased up to 10. Interesting, and no doubt useful for unique situations.

The AnaBat Scout comes with the free version of Anabat Insight software, which you may download Here (there is a version for Mac as well as Windows). You will notice that the User Manual may also be obtained on that Web page.

I installed the 2 AA sized batteries required, as well as a new 16GB SD memory card (I happened to have available); and pressed the OK button to power on. The user is greeted with the OLED display, featuring text (and icons) of a yellowish-green colour.

Changing the brightness level, from High to Low


My (point & shoot) camera did not give an accurate representation of the display. It appears a bit too bright in this video. In reality, it looks clear, crisp, and not too bright.

I was glad to see that the display brightness is adjustable, from High to Low. Because I prefer to keep bat detector displays as dim as possible; especially when in the field.

Short video of powering off The AnaBat Scout.

To power off the detector, hold down the OK button - The display will read "Would you like to shutdown?" And you press the Yes soft key (on the right).

The Anabat Scout has the ability to have it's sensitivity (event trigger) changed; you may choose Low, Medium, or High (High is the default setting). Very useful, for those instances when bats are flying low and/or close.

Minimum frequency is 10 kHz, and maximum is 160 kHz (both are the default settings). Either/or may be adjusted to suit the situation, under Trigger Settings on the unit. Also by default, the Recording Mode is set to triggered mode; and this may also be changed to Constant Recording Mode, when and if needed.
 
Some of the features of The Anabat Scout, which I particularly like as seen on the display are: The GPS indicator, Number of Satellites in View indication, % of SD Card Memory Available, and Tuned/Peak Frequency.
Again, those doing emergence surveys will be pleased to see the Out and In Count.
A very clear representation of these features, may be seen on Page 6 of the (freely available) User Manual.
I would encourage the reader to have a look at pages 12-14 of the Manual, which describe further opportunities to fine tune aspects of: Triggering, Recording, File preferences, and various Audio Settings. 
For audio output - You may choose between heterodyne, frequency division (which is divided by 16) - Or, if using earphones, both! In other words, heterodyne is heard in one earphone, whilst FD is heard in the other.

Some additional features which I liked were: 

When a recording is triggered, a recording symbol appears, on the bottom center of the display.
The Heterodyne auto-tune - Described on page 14 of the User Manual. 
Transect Mode - Which uses the built-in GPS to save your track as a .gpx file (it checks GPS points once per second).
The Anabat Scout also has the ability to run diagnostics on itself (should the need arise).

A user may also subscribe to receive email alerts, whenever Scout firmware is updated; very neat!
The process of updating the firmware is just what you might expect: You copy the (scout.adx) file to the root of the SD card, insert SD card, and power on the unit. At which point, you will be asked "...Would you like to update now?". At which point you'd press Yes, and wait for it to complete the update. After which, it will restart itself.

During my extensive testing, I found the the AnaBat Scout's microphone to not only be substantially sensitive, but to produce accurate-sounding results (audio tones) from the front-facing speaker. Careful analysis of the recorded bat calls, further confirmed the sensitivity, range, and overall accuracy of it's recording abilities.

I found The Anabat Scout to have sensitivity and range comparable to many other Professional-level bat detectors. Especially within it's price range. A couple of species of my local (North American) bat species, were recorded at distances of 100 meters.
See pages 20 to 21 of the User Manual, for a concise answer to the question: How far away can a bat be detected?

Pros:
  •  Bat emergence In and Out Counter (separate button for each).
  •  Excellent sensitivity and pick-up range of bat calls.
  •  Pleasing (and adjustable) OLED display, preserves a user's night adapted vision; while providing live pertinent information.
  •  GPS/transect and logging capabilities.
  •  Adjustable sensitivity, and frequency range.
  •  All metadata recorded on The Scout is saved to files in the GUANO (Grand Unified Acoustic Notation Ontology) format.

Cons:
  •  Not weatherproof.
  •  Glow-in-the-dark buttons need improvement.

The Scout has excellent features of value to Ecologists and Bat Workers who are tasked with doing bat emergence surveys. In addition to many of the capabilities one would expect from a Pro-level bat detector, it possesses some which are specifically geared towards bat emergence surveys.
The Anabat Scout also records metadata -
All metadata recorded on The Anabat Scout, is saved to files in the GUANO (Grand Unified Acoustic Notation Ontology) format. This format is now the industry standard in the field of bat acoustic studies. Details regarding this configuration may be seen on page 20 of the User Manual.



More will be added to this (part 2) Anabat Scout review soon...

Amoung the next items to be reviewed here, are some interesting new microphones designed by Titley, for use on their AnaBat Swift detector.

Happy bat detecting!

Review: The AnaBat Scout From Titley Scientific Part 1 of 2

Review: The AnaBat Scout From Titley Scientific Part 1 of 2

The AnaBat Scout is a full spectrum bat detector, designed to be used for active bat detecting. 
I will state from the start, that I have used it as a passive bat recorder on more than one occasion, and acquired excellent recordings of bat calls.

The Anabat Scout arrived directly from Titley (Australia) very well packaged & packed. The box which contains The AnaBat Scout is seen in the photo below:

AnaBat Scout box, along with included Quickstart User Guide


The AnaBat Scout is 150mm long by 74mm (at it's widest point) and 38mm thick. For U.S. readers, this translates to 5.9" x 2.9" x 1.5" in thickness.
It weighs 160 grams (5.64 ounces) without batteries installed. NiMh, Alkaline or Lithium type batteries may be used. The AnaBat Scout runs on 2 AA size batteries.

If purchased directly from Titley Scientific, The AnaBat Scout is going for $850 U.S. dollars.

NHBS also has them in stock:



As well as Wildlife And Countryside Services (UK)

The AnaBat Scout has the ability to listen to bat calls in real time, in either: Heterodyne, auto-heterodyne, or frequency division audio modes. 

It also has the ability to record in either zero crossing or full spectrum mode. The AnaBat Scout also features a built-in GPS for transect mode and geotagging. It also has an In & Out bat counter, with automatic time stamping and geotagging; as well as the ability to record voice notes. 
These are all excellent features for bat surveys.

The AnaBat Scout comes with a free version of AnaBat Insight software. It is also provided with a lanyard, a protective carry pouch, and glow-in-the-dark buttons.

The AnaBat Scout has an easy to use robust design, with a front-facing mic element. With the Mic for voice notes located just above the (OLED) screen, facing the user. It has an easy-to-navigate keypad, located just beneath the display.

Before you begin recording bats with the AnaBat Scout: It is advisable, to set the current time zone. If this isn't done, the time stamps on your recordings will be incorrect. 

The AnaBat Scout worked very well as an unattended recording device, despite the low temperatures.


The AnaBat Scout would serve as an ideal unit for both Professionals; and amateur naturalists, who enjoy using a full-featured bat detector.

The AnaBat Scout would be an excellent tool for Professional Bat Workers who frequently perform roost surveys and/or emergence counts, since it has a built-in In and Out Counter - More on this, in Part 2 of the review.

The construction of the AnaBat Scout itself, feels very solid. There are no protruding parts on the unit, which you need to worry about breaking off, or damaging. 
The Scout packs a lot of technology and features into a fairly small, and easy to handle unit. I've found The AnaBat Scout a joy to use, with it's slightly curved design fitting quite comfortably in the hand, and it's front-facing microphone. 

Of course the omni-directional microphone itself, is larger in size than the opening (seen upon closer look at the front panel). This is a clever way to keep the mic element protected, from any would-be harm encountered while outdoors.

Once your main settings have been set, and your preferences selected, it only takes a few button presses - To begin monitoring, recording, or even un-attended recording (one of my favorite methods). The process of using The Scout will be covered in detail in Part 2 of this review.
After an evening of recording, and inserting the unit's SD card into the laptop: I was able to easily select and manage large numbers of bat recordings.

I did manage to run through one set of AA-sized batteries...This is the warning displayed, when batteries are low.

I'm happy to report, that when the Anabat Scout arrived here (in the Northeastern U.S.) in late October (2019) my local bats were still active; and they provided me with excellent recording opportunities!
Overall, I have been very pleased with the overall performance and accuracy of The AnaBat Scout from Titley. I also admire the fit, finish, and attention to detail demonstrated in it's design; and functionality!

Much more to follow soon, in Part 2 of this review. Which will cover out-of-box set up, ease of use, recordings & resulting spectrograms, etc.

Happy bat detecting!

Review: Bat Call Identification Software (BCID) Part 2 Of 2

Bat Call Identification Software Review (BCID) Part 2 Of 2

During my most recent, extensive testing, I've found BCID software to be very accurate when identifying (predicting) bats down to species. It provides a neat / uncluttered result file (.xls format) along with the relevant accuracy (estimate) data. Which is to say, how "sure" BCID is, as to the ID of the bat species.

The software installs easily, directly after downloading. BCID software has no problems handling files/recordings from all major bat detector manufacturers.
BCID was designed to handle large sets of data; and is capable of analyzing approximately 2,600 call files per minute. 

By default, BCID automatically analyzes all of the zero-cross recordings contained in the user specified file folder.

It is compatible with both zero-crossing and full-spectrum recordings of bat sounds. Selecting your detecting location, under the Species tab, is straightforward. Two states are shown, in my example screenshots below:


 
New York

South Carolina


The User Manual for this software program, is accessible from withing the software itself. By clicking the 'Help' tab; the 7th (and last) tab on the right hand side of the main screen.
Clicking the 'View Manual' button brings up the latest User Manual (Ver 2.8a, 4-29-19). It is produced in a very well laid out, and easy to read format.

Points of interest in the BCID User's Manual are:

  • Pages 4 -to- 18 clearly describe the functions of each of the program's main tabs.
  • Page 19 and 20 provide tables of accuracy rates (examples). Demonstrating the program's ability to accurately discriminate between bat species.
  • Pages 21 and 22 cover troubleshooting, suggestions, and the process for reporting any bugs a user might encounter.
I should add, that during my extensive test period, I did not encounter any bugs.

Pros 
  • Has a very easy to use, simple interface.
  • Uncluttered, clearly readable results report.
  • Printing results/reports is 2 clicks away.

Cons
  • More expensive than it's closest competitor (Kaleidoscope).
  • Customization of ID sensitivity, settings, etc. not as easy as K-Scope.

BCID Software may be ordered directly from The Bat Call Identification Website.

It's very refreshing to use a bat call ID software as uncluttered and easy to use, as BCID. I enjoy printing out the results/report files listing the bat species recorded.

There are still many Professionals, Ecology Firms, and Organizations who prefer to use zero-crossing recordings for their bat surveys, and sometimes even research. In situations where ZC format is the predominant method of recording, BCID software should be given very serious consideration.

Since I am also in the process of reviewing new bat detecting instruments; chief among them being The AnaBat Scout from Titley, as well as optional microphones (designed for The AnaBat Swift) I expect to be adding some more info to this part of The BCID software review.

Until then,

Happy bat detecting!

A Recent Arrival! The AnaBat Scout Bat Detector From Titley Scientific!

I'm pleased to report the recent arrival of the latest (new) bat detector offered by Titley Scientific - The AnaBat Scout!

I'm happy to report, that it arrived here (from Australia) several days ago. And made it here (to NorthEastern U.S.) in time to record some bats!

The AnaBat Scout arrived well packaged & protected from Titley Scientific

There were bats recorded as late as October 30th (none on the 31st, I'm sorry to say). This is great news for the upcoming testing and review.
For now, I can say that it is a charming bat detector, with many nice features which Pros will enjoy! Bat calls (in Heterodyne output mode) sound great! Volume for audio output goes from 0-25. I found it to be quite pleasing at a setting of ~18 for unattended recording (near an open door or window).


Having a quick look around with The AnaBat Scout bat detector from Titley

Bat detecting is on-going, and as always, I will hold out hope on any nights of 50 degrees Fahrenheit or above. I'm also excited about two additional microphones, received for testing, from Titley Scientific. These are for The AnaBat Swift (recently reviewed here). I will probably need to resort to artificial/electronic bat calls for testing; more on those later.

In the short video clip below, we see The AnaBat Scout in action - As it first senses (and begins recording) a bat call, the recording activity indicator may be seen illuminating. A round indicator, in the lower center of the display. You can also hear the (heterodyne) sound produced as the bat flies by. 
This happened to be one of my "resident" Big Brown Bats (Eptesicus fuscus); and it was flying fairly close.

(upstate New York)

In addition, on October 30th, The AnaBat Scout got a great recording of a bat, from a distance of approximately 35 meters. It was at 7:20 PM (19:20), sunset was at 5:52 PM, temperature was 59 Deg. Fahrenheit, humidity of 99%, with wind from SSE at 6 MPH.
 
Part 2 of 2 of The BCID software is also in progress...

BCID Software Version 2.8B Review (2019) Part 1 Of 2

BCID Version 2.8B Review (2019) Part 1 of 2

BCID stands for Bat Call Identification; it is Professional-level software for the automatic analysis and identification of bat species, via recorded audio.

BCID is currently used by several agencies, Ecologists, Professional Bat Workers, and Researchers; to facilitate identification of recorded bat sounds.

I'd written a review of this formidable bat call identification software once before, back in February 2013. And thought it would be a good time to re-visit this application, and write an updated overview for 2019.

BCID has the distinct accolade of being one (of only two) software applications endorsed by  The U.S. Fish And Wildlife Service. More specifically, it is approved by The USFWS for conducting surveys, for the following bat species: 

The Indiana Bat (Myotis Sodalis) - USFWS Link
The Northern Long-Eared Bat (Myotis Septentrionalis) - USFWS Link

The other software, is Kaleidoscope from Wildlife Acoustics.

At the time of this writing, BCID is available in two versions:
A cursory look at BCID software, for someone who hasn't seen it before, reveals a rather simple-looking (GUI) interface:


Clicking on the BCID Eastern USA link (just above this screenshot), will take you to The BCID Web page, which features (scroll-able) example screens of the application.

To see a list of species which BCID currently covers, and to confirm price ($1479 US Dollars at this time) for 2 Seats / 2 computers, you may click Here.

BCID Software has been continually improved in the years following it's initial release, in 2007. Some of the very latest updates, may be seen Here.
It is a Windows-based software (32 and 64 Bit), which allows a user to quickly and accurately analyze large numbers of bat calls.
The user interface is simple but effective, and very easy to use. The current version of BCID is Version 2.8b.

BCID software should be given serious consideration, by anyone in need of a robust, easy-to-use, and accurate bat call identification software.
It is particularly well-suited to Ecologists, Bat Workers, Researchers, and anyone wishing to have bat calls identified.

The easiest way to use this software, is by starting with ZC recorded bat calls. However, as you'll see, .wav files are almost just as easy to process:
  • From the default screen, click the 'Add Folders to Project' button, on the lower left-hand-side.
  • Drill down to the location of the (ZC) file folder containing your recordings.


In this screenshot/example, the location happens to be 'BCIDConversions' folder.*

  • Click the Species tab, and select your Country, and State. Your local bat species will be displayed. The (already checked) names of the bat species, are also un-checkable; if you have the need to omit a species from being identified.
  • Click the Project tab, in order to make the original bottom tabs visible again.
  • Click on the Identify Calls tab (lower center of screen).
  • After (typically) a few seconds, the interface will look like this:

...Identification process complete.

  • When using the default settings, several report files are created. As seen in the screenshot below:

Assorted files created by BCID (by default) include .anl (AnaLook), .xls (MS Excel), and .txt (text) files (A different folder was used in this example).

  • As evidenced in the screen capture above, when accepting the default software selections, various files are created. As well as the individual bat recordings being converted to .ZC. In my particular case, the .zc files have automatically associated themselves with Kaleidoscope software; which happens to reside on my laptop as well.
  • In general, I've always found BCID software to be fast, accurate, and very convenient to use. There is certainly no steep learning curve here!

*Note: The BCIDConversions folder is automatically created when using BCID's WavToZero feature. And the files chosen for conversion are converted to ZC, and deposited there.  
If you recorded your bat calls in Full Spectrum mode, BCID software has a convenient 'WavToZero' feature. It's a permanently available Tab; 5th one from the left-hand-side of the interface. As the name implies, it allows you to select multiple files (not folders, but multiple individual files) for quick conversion - From .wav files to Zero Cross files.





As seen in the screenshot below, the report files which BCID creates, are in .xls format. I have always found this to be a very welcomed feature; especially because printing the file is so seamless.

For this particular example, I intentionally selected a group of recordings with very little bat activity. For the sake of clarity. Future screenshots, in Part 2 of this review, will illustrate much heavier call volume. Which for many of my readers, is a more common occurrence. 


The output (.xls) files which BCID creates, that is to say, it's report/listing of bat species detected, has always been one of my favorite features.

Very convenient! Looking forward to completing Part 2 of this review.
Stay tuned...

Happy bat detecting!

Review: The AnaBat Walkabout Bat Detector Part 2 Of 2

Review Of The AnaBat Walkabout Bat Detector - Part 2 Of 2

The AnaBat Walkabout bat detector from Titley Scientific, is a high-quality bat detecting/recording device, with an abundance of features.

One of the reasons for this, is The Walkabout is built upon an Android tablet. Not an off-the-shelf / consumer tablet, but one specifically designed (from scratch) to be The AnaBat Walkabout. Being built upon such a versatile foundation has it's advantages.

One of the things which I admire about The AnaBat Walkabout, is how robust it is. It is very reliable. Not prone to crashing, or freezing-up, the way a low-cost tablet might.


An excellent guide to the features, buttons, and ports of The AnaBat Walkabout (Thanks to NHBS)
    

During the testing of The AnaBat WalkAbout, I left the microphone's sensitivity at the default setting (as from the factory). 
If (you are fortunate enough) to have bats flying low, or close to you: You may want to change the sensitivity, to a lower setting. If not, you are likely to end up with spectrograms containing prominent harmonics - As seen in my example below:



A (partial) screenshot, of a bat recorded with The Walkabout. As viewed with AnaBat Insight software.


As a continuation from Part 1 of this review, here are some additional specific features which I particularly like:


  • All of the methods available for bat detection: Listening to the audio of bat calls, which are - FD, Het, FS, TE.
  • The recording methods available: Zero-Cross, Full Spectrum, and a combination of both (simultaneously).
  • Being able to select a frequency range as low as 5kHz - Enables me to target and record many species of Orthoptera (singing insects).
  • Additional (2.5mm) jack for use with external (Ultrasonic) Mics.

If you enjoy tinkering with electronics - especially, DIY Ultrasound Mics (as I do), then you may find the last bullet point above particularly interesting. 
I will inform you, that all of my early attempts/tests, with DIY microphones, were unsuccessful. This need not deter the reader from carrying out their own experiments.
I eventually came to the conclusion, that it would be best to stick to purchasing the official Titley microphone adapter and Mic, if there is a need.

In my case, having wasted so much time trying to build a working Mic, only bolstered my appreciation of the quality recordings captured with The Walkabout's built-in (Knowles) microphone. As is, The Walkabout is able to pick up bats at respectable distances; and produce excellent spectrograms while doing so.

Here is the optional Microphone Adapter, made for The AnaBat Walkabout from Titley:



Link to Titley's page on it Here.


The Walkabout's battery life is stated as being 8-12 hours (in The User Manual). This matches my experience while testing as well. 
I plugged The Walkabout into the mains, with a completely flat battery, at 7 PM - And it was fully charged at 12 AM. This was early-on in the testing phase (first week of use). Actual discharge/charge times may vary (most likely, improve) with regular use (since it is a rechargeable, Lithium ion battery).

Zooming-in on the (combo) FS/ZC displayed in Insight software

What's it like, getting and using The AnaBat Walkabout? 
Allow me to make (another) analogy - Back when I was into the keeping of Mini-Reef aquariums. Something which was a lot of fun, was buying a piece of Live Rock... After situating it in the tank, and as the days went by: I would discover several fascinating & colourful creatures inhabiting the nooks & crannies of the piece of rock. And it was like little unexpected bonuses!
Well, it's a bit similar to using The Anabat Walkabout, as you:
Read the manual, and start using it - You begin to discover all these neat little features; which you didn't realize were there. 

A great example of this, is when I discovered 'Basic Mode' (shown below). It is a completely different looking interface (listening in heterodyne mode) while recording. With several neat features: Live Temperature, Lux, and Humidity sensor readouts, as well as an electronic compass! 


In summary, I'd place The AnaBat Walkabout in the same class as other "Alpha" bat detectors; such as: 


If you were considering one of these, you would be remiss not to include The AnaBat Walkabout on your list of potential prospects. 
In fact, depending on which specific abilities, and features you need or want - You'll probably find that you prefer The AnaBat Walkabout to the others.
There's no denying that The AnaBat Walkabout has many more features than those listed above. 
 
The Walkabout is very easy to use:
  • Press Power on button, for 2.5" - AnaBat insignia comes up as a splash screen.
  • Check your Audio and Recording method preferences. 
  • Tap the Microphone icon, to turn on the Mic (icons turn yellow to indicate "On" status.)
  • Select Auto or Manual recording...
  • And you are detecting/recording bats!

I have found The AnaBat Walkabout to consistently produce accurate, and detailed recordings of bat calls. Which in turn, facilitates production of excellent spectrograms.

Note that you may use/analyze bat recordings made with Tiley detectors on bat call identification software (such as BCID or Kaleidoscope). I've had no issues doing so. But, you cannot view bat recordings made with other manufacturer's  detectors in the free version of AnaBat Insight - You may view recordings from any detector when using the paid (full) version of the software.

Here are some links to the additional (optional) accessories, offered by Titley for The AnaBat Walkabout:

Screen Protector

Silicone Case

USB Power Bank
  
Microphone Adapter

The next bat detector to be tested and reviewed will be The (brand-new!) AnaBat Scout from Titley Scientific. It's always exciting to test and review a brand-new bat detector; and I'm really looking forward to it!

Until then...

Happy bat detecting!
