Hi, all. Agreed with everybody that it's fascinating to observer these mid-winter movements. (And I'm a fan of mid-summer movements, too!) Here's a tidbit from Jon Dunn and Kimball Garrett's Warblers (Houghton Mifflin, 1997): "Unlike most other warblers, Yellow-rumps may move considerably through the winter season (facultative migration), probably in response to shifting food resources; this movement even involves nocturnal migration behavior more typical of spring and fall." Here in Colorado, we sometimes hear American Tree Sparrows flying at night in the dead of winter. (Long story short: movements possibly associated with the midwinter prealternate molt???--now known to be more extensive that was previously thought.) And imagine if we listened with the same intensity that we do in Sept. and Oct.! Ted Floyd tfl...@aba.org <mailto:tfl...@aba.org> Lafayette, Boulder County, Colorado

I think birds move around at night year-round. For example in Jan and Feb, I record the flight calls of Snow Buntings during the pre-dawn (0430-0700) of many mornings. Last winter I recorded Common Redpolls also in the pre-dawn. I occasionally will record American Robins at this time. I seldom (never Snow Buntings) get these birds on the ground during my daily dawn eBird counts.

Spring migrants begin moving in February, and "fall" migrants will sometimes move any time in winter if they get pushed out of northern areas by cold weather or snow. This has been a mild winter, so there were likely more Killdeers lingering at northern latitudes than usual. Still, it's really cool to hear a nocturnal migrant in mid-winter, and great to document it! best wishes, Michael Michael O'Brien Victor Emanuel Nature Tours www.ventbird.com ________________________________ From: "Andrew Albright" <andrew.albri...@gmail.com> To: "nfc-l" <nfc-l@cornell.edu> Sent: Tuesday, February 7, 2012 10:13:54 PM Subject: [nfc-l] First night flight of 2012? I just got back from running (more than 3 hours after nightfall) and I heard a Killdeer fly overhead! I'm in southeastern PA and this is very rare bird in the winter for this county. So....does this count as a night flight?
