[huatulco]

I recently bought a recorder and tried it out in Huatulco, Oaxaca, Mexico. Only problem was I could not see the birds! Any ideas on what type of birds these are?

Hi,
Without knowing what your sound is, I made a spectral analysis of your recording. Your recording appears to be unsaturated wich is a good thing. I can see that the individual sounds appear in the range from 2 to 4 kHz, but I would assume that your bird was singing with notes that were higher than 4kHz, which is an unfortunately lowcut off frequency. I would guess that some higher notes may have been lost and the rattle like notes had a higher pitch to them?

Were there one or many birds? and in what kind of a place were they singing? residential area, grassland, bushes, heavy forest.... Did you see any birds there?

Hi,
There probably was other sound that got lost when I tried to clean up a bunch of noise that was picked up when I did the recording. I made the recording in a very natural setting with no buildings, traffic, other people etc. It was in a national park and quite heavily wooded. There were a number of birds singing at the same time. There were a lot of birds in the area at the time but did not keep good enough records to remember exactly which ones I did see. Taking photos was my priority and am afraid I did not take the recording seriously enough!

I am planning on taking another trip to Huatulco in either March or April and hope to get better recordings at that time. Hopefully I can isolate sounds better this next time.
