[Tweeters] Black-throated Gray Warbler nest question - clarification

Hello again Tweeters,

I realize that my message below from a couple of weeks ago, in which I asked about nest proximity given a foraging observation of a Black-throated Gray Warbler, could have been interpreted to mean I wanted to find and photograph the nest, potentially disturbing the bird.

My purpose in asking—which I should have clarified—was to learn how big a radius around the observed location should be protected from disturbance. I'm working with our local park steward to minimize nest disturbance by invasive-clearing groups, and it would be helpful to be able to tell her how far away her crew should stay from likely nesting areas.

Thanks so much for any assistance or perspectives.

Good birding to you,
Trileigh

Subject: Black-throated Gray Warbler in Lincoln Park today

Hi Tweets,

Although these gorgeous little guys are supposed to be common summer residents, I've not had much luck photographing them. Finally today, while trying to keep my eye on one of the multiple elusive Pacific-slope Flycatchers that'd been calling loudly but hiddenly, another movement caught my eye. This Black-throated Gray was gathering nesting material from an upturned root mass from a tree downed in the 2006-ish windstorm (whose 90 mph winds bowled over a number of our Lincoln Park forest greats).

I'm curious about how widely away from their nest they do their foraging. For instance, could I expect that there'd be a BTYW nest within 10 yards? 50? 2?

Secondly, Sibley indicates that the adult female would have a black band across her throat, the adult male has the eponymous black throat, and the first-winter juvenile has a pale throat. However, he also says the first-winter bird is generally August-March, so it seems kind of late for that now in mid-May. Or do they often retain their juvenile plumage longer? This bird has a pale throat and no black band.
