All:

Eric Mills and I, without having seen Hans Toom's message, went to the W. side
of Cow Bay Lake yesterday mid-day and found the Little Egret loafing amidst a
bunch Ring-billed Gulls on a bar just off the shore. I took some distant
digiscope shots at maybe 200 m., and have posted one, with insert, on the
NS-RBA photo site.

Other birds of some interest included numerous Short-billed Dowitchers
(including one group of 250 at Grand Desert, HRM, and another group of
hunndreds, hotly pusued by a very pale-backed adul Peregrine. We saw a few
apparent _hendersoni_ among the dowitchers, but their underparts are beginning
to fade. A group of 10 Hudsonian Godwits, two Black-headed and two Bonaparte's
Gulls had returned to the estuary on the Conrad's Beach road,

The Little Egret is an adult, but its small head plumes (filoplumes) are much
worn, and there is maybe only one shortened thin one left. The bird has a little
bit of olive yellow immediately in frot of its left eye. This is presumably not
a result of a trace of Snow Egret genes (the two species may have hybridized in
the W.I. and FL), but a remnant of the yellowish or reddish that develops in
high breeding condition. (Some may remember that our firat Little Egret had, at
first, all olive-yellow lores.)

We have stil not solved the identity of the other small egret. The twosome was
photographed by the Reids on the 16th. I suppose it is not impossible that two
of these Old-World invaders could have migrated n. from the Caribbean to
connsider breeding here. (We're at the latitude of s. France, where they breed,
and one summered for some years in our briefly established Showny Egret colony
on Bon Portage I.}

Cheers, Ian
