Bird
Sound Resources
Macaulay
Library
of Natural Sounds at Cornell's
Lab of Ornithology - The world's largest
collection of recordings of animal sounds is digital, and much of
the collection is available for listening online. Download Raven sound
analysis software and you can visualize sounds from the library as
spectrograms on your computer.
Xeno
Canto - A very impressive
user-maintained database focusing on sound recordings of diverse taxa,
all available for listening online or for downloading.

Sound
Analysis Software
SYRINX by John
Burt - This is the software we use most extensively in the Mennill
Lab. It is a very versatile software package for visualizing and
measuring sounds. I use Syrinx to annotate sounds and conduct basic
time and frequency measurements. Syrinx is also a very effective tool
for interactive playback and automated sound recognition.
AviSoft
SASLab - This is excellent commercial software for analyzing animal
sounds. It is expensive but it is powerful. In the Mennill
Lab, we use this software for automated sound measurements and
spectrogram
cross-correlations, among other things.
Raven
- Raven is Cornell University's Bioacoustics Research Program's sound
analysis
software. There is a free version called
Raven Lite, and a full version called Raven Pro which is available for
purchase.
X-BAT - The eXtensible
BioAcoustic Tool from Cornell's Bioacoustics Research Program is free
open source software that can be run within MATLAB; it is very powerful
for advanced sound analyses.
Adobe Audition
- A second important software tool in the Mennill Lab. This software
was designed for
manipulating music, but it proves useful for visualizing animal
sounds.
In particular, Audition is very effective for frequency analysis,
representing sounds as spectrograms, and spot filtering. We use
version 2.0, but there is a newer version 3.0 now available.

Radio
Telemetry
Please see
my radiotelemetry
page for advice on how to radiotag small birds.
Holohil
Systems Limited - A dealer of radio transmitters in Ontario
Canada. I have used Holohil's LB-50 radio transmitters
to
follow Black-capped Chickadees.

| Costa
Rica and Santa Rosa National Park
The
homepage for the Area de Conservacion Guanacaste,
an outstanding national park where I conduct much of my tropical
research. Santa Rosa National Park is contained within the ACG.
Investigarodes
ACG - A website for scientific researchers working in the Area de
Conservacion Guanacaste .

Recording Devices and
Playback Devices
Wildlife
Acoustics - We use Wildlife
Acoustics Song Meters extensively in the Mennill Lab. They are an
excellent product for automated recording, and the people at Wildlife
Acoustics are really helpful.
FoxPro
Speakers - I am not a
hunter, but I recommend Fox Pro's "Digital Calls" (these are
field-portable loudspeakers that include built-in
memory to store your sounds and a remote control that you can use to
operate the loudspeaker
remotely).
