Re: [nfc-l] Chipping Sparrows, eastern Boulder County, Colorado - and cuckoo lore

2013-07-23 Thread Kenneth V. Rosenberg 
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….

Fascinating to think they disperse a night between broods. Meanwhile Yellow 
Warblers zeeping everywhere- should be a mass exodus tonight.

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.

Re: [nfc-l] Chipping Sparrows, eastern Boulder County, Colorado

2013-07-23 Thread Ted Floyd 
Hi, all.

[Chipping Sparrow just flew over at 4:10 a.m., Mountain Daylight Time,
i.e., during astronomical dawn, eastern Boulder County, Colorado, USA,
Tuesday, July 23rd.]

Cool observations and speculation from Ken. One point of clarification: In
contrast to the situation with Ken's thrashers, tanagers, etc., I wouldn't
say that western Chipping Sparrows are dispersing at night between broods.
Rather, they're dispersing at night from their one brood (I think) and
their faraway molting grounds.

It's been slow tonight, with just two Chipping Sparrow flight calls since
about 2:30 a.m. But it was nice to hear the first nigh-migrant Lark Sparrow
of the season, about 20 minutes ago.

There's definitely some mid- summer shuffling going on, as I've had singing 
Wood thrush, Veery, Brown Thrasher, and Scarlet Tanager in new places this past 
week. Fascinating to think they disperse a night between broods. Meanwhile 
Yellow Warblers zeeping everywhere- should be a mass exodus tonight.
