Re: [nfc-l] help with a mystery call from a few years back

Andy, I think you may have been on the right track with shorebird. It reminds me of an interaction or chase call of a small Calidris sandpiper (presumably Semi/Least in your area). Michael Michael O'Brien Victor Emanuel Nature Tours www.ventbird.com On Feb 22, 2013, at 6:48 PM, Andy Martin

Re: [nfc-l] Call ID?

Hi Will, The relatively low pitch and rough quality sound just fine for Gray-cheeked. This is a good illustration of how some Gray-cheek calls can be less arched than "typical". best, Michael Michael O'Brien Victor Emanuel Nature Tours www.ventbird.com - Origin

Re: [nfc-l] head-scratcher

Benjamin et al., This one also sounds fine for Barn Owl in terms of tone, pattern, etc., and not right for Great Horned. But odd to hear it doubled like that. They usually give single, well spaced notes. best, Michael Michael O'Brien Victor Emanuel Nature Tours www.ventbird.com

Re: [nfc-l] Nocturnal flight calls, Colorado's Front Range, 3+ years of data

Hi all, Andrew brings up an interesting question about midsummer nocturnal flight calls. As he suggests, I think there are a variety of different behaviors going on here. In the case of cuckoos, their midsummer nocturnal flight calls usually seem to be associated with good breeding

they seem to be less vocal. It would be interesting to know what others have observed and if the situation is different elsewhere. My guess is that the main difference, if any, is that robins call more frequently in certain situations and fly more quietly in others. good listening! Michael

Re: [nfc-l] passerines with sexually dimorphic flight calls?

All, I have the impression that Blue Grosbeak and Passerina buntings are sexually dimorphic in their flight calls, higher pitched in females, lower in males, but have never tested this in any rigorous way. Has anyone else looked into this? Michael O'Brien - Original Message
