We have many birds here in north america with a similar chip (American
Robin, Western Meadowlark, ect.) Looking at a sonogram we find these
are broad banded. They are used to localize a ground based threat. You
might also listen to see if your birds do a high frequency, nearly pure
single tone zeeeet when a flying hawk comes by. This sound will be very
rare, but keep your ears open for it!

Subject: RE: [Nature Recordists] A bird's response to ATRAC
here in india, many of the small birds use a
highpitched and quite loud chirp (but longer than a
chirp would be)as an alarm call. it is so species
unspecific that it has hard to tell which bird has
called. you hear it most often if you are close to a
bulbul nest, or there is a prowling cat nearby. i will
try and record some and post them one day. i now have
a telinga reflector, thanks to eric benjamin!
