Yes, most of my YEWAs have been zeeping during the day (including one out my window right now), and especially around dusk. I'm still not hearing much at night from my house, but I just listen (sporadically) and don't have a recording set-up.
I remember you talking about the molt-moivements of Chipping Sparrows, Ted, and wondering if dispersing double-brooders in the east do a similar thing -- at least sometimes. And lest we all think we discover new things, here is an excerpt I recently discovered while doing research on wintering migrants for a book project -- Bent's Life Histories never ceases to amaze me: On "the mid-summer mid-bight and mid-sky gyrations of the Black-billed Cuckoos" (from a letter from Gerald H, Thayer (1908) in sw. NH: "several years before we discovered the nocturnal-flight phenomenon, we bean to be puzzled by the extreme frequent of Cuckoo calls on summer nights…. They uttered bot the cow-cow notes and the rolling guttural call; but the guttural was much the commoner of the two, except on dark foggy nights, when the case was usually reversed….The birds were often so far up as to be only faintly audible when directly overhead,… and this on a still night would seem to mean an elevation of at least a hundred and fifty yards. On the evening of July 11…. I heard this liquid gurgle note overhead between thirty and forty imps in the course of about three hours, during half of which time I was afoot on the road." 1908! And I thought Bill Evans discovered the NFC of Black-billed Cuckoo while delivering pizza in Minnesota….

Re: Yellow Warblers zeeping everywhere. Same here (Boulder County, Colorado), but rarely at night. I don't think I'm just missing them, since I'm perfectly able to hear (and record) them by day. They just don't seem to call at night; maybe they just don't move at night, either, out West. Probably just one of those east-vs.-west things, eh? Ted Floyd [email protected]<mailto:[email protected]> Lafayette, Boulder County, Colorado Fascinating to think they disperse a night between broods. Meanwhile Yellow Warblers zeeping everywhere- should be a mass exodus tonight.

A quick check-in here from somewhere other than the Cayuga Basin... :-) Chipping Sparrows are moving over Lafayette, eastern Boulder County, USA, in the 2am hour right now, Saturday, July 20th. We believe that these are birds bailing on their mountain breeding grounds for literally greener pastures in eastern Colorado and western Kansas, where they molt. Regardless, it's an annual phenomenon, beginning in mid-July (first nighttime detection this year for me was July 16th), in the night skies over the Denver metro area, and it's fascinating to witness.
