I could hear 2 or= 3 from almost any wooded location on the island. They must have still been= on territory. This is in contrast to the low numbers of the other warblers= that were heard. The expected Swainson's Thrushes were comparitively quiet= =2C with only one singing and calling briefly. Also of interest was the app= arent thriving Black-guillemot colony and the decimated Leach's Storm-Petre= l population=2C see notes in eBird Checklist: http://ebird.org/ebird/view/checklist/S30870587 --- =20 Alix Arthur d'Entremont BSc Geomatics Engineering 292 Abbott's Harbour RoadMiddle West PubnicoYarmouth Co.=2C Nova ScotiaCana= da B0W 2M0 Phone: +1 902 762 2082Mobile: +1 902 307 0373 =0A= e-mail: alixdentremont@hotmail.com =0A= Bird Photography http://www.flickr.com/photos/alixd/Website http://alixdent= remont.blogspot.ca/ From: lance.laviolette@lmco.com To: naturens@chebucto.ns.ca Subject: Re: [NatureNS] Early Warbler Movement Date: Tue=2C 26 Jul 2016 16:44:53 +0000 =0A= =0A= =0A= =0A= =0A= =0A= =0A= =0A= Hi Everyone=2C=0A= =0A= I agree with the thoughts that have been put forward so far. Many of the bi= rds in the interior of NS and NB have become mostly silent=2C=0A= fledged their young and moved away from their breeding areas to areas wher= e their young will continue to build strength for the trip south. On the co= astal islands=2C some species still have young in the nest in mid-August (B= lack-throated Green Warblers and Golden-crowned=0A= Kinglets for instance) so they are probably the late season representative= s of their species that John detects.=0A= =0A= Historically on Brier Island=2C there have been some pulses of migration of= mixed song birds in late July and early August. These are=0A= fairly uncommon however. Mid-August onward is when the big movements of so= ng birds are seen=2C starting with the flycatchers and early moving warbler= species such as Yellow Warblers and Common Yellowthroats.=0A= =0A= =0A= All the best=2C=0A= =0A= Lance=0A= =0A= From: naturens-owner@chebucto.ns.ca [mailto:naturens-owner@chebucto.ns.ca]= =0A= On Behalf Of James Churchill =0A= Sent: Tuesday=2C July 26=2C 2016 9:58 AM =0A= To: naturens <naturens@chebucto.ns.ca> =0A= Subject: EXTERNAL: Re: [NatureNS] Early Warbler Movement=0A= =0A= =0A= =0A= folks=2C =0A= =0A= =0A= =0A= =0A= =0A= A few related observations from conducting intensive bird surveys in the Fr= edericton area for the last two weeks.

Some of the warblers seen could have been migrants mov= ed in from elsewhere in the province=2C and what we saw were usually in mix= ed groups=2C=0A= but there were few. This suggests that the warblers that move into those = areas have not arrived yet or those that were there have moved out altogeth= er. It will be interesting to compare to what is being seen in the southwe= st of the province by other birders=0A= and on Brier Island.

Do you think these birds have dispersed to=0A= other places in the province or that they have left the province to go sou= th for the winter? Normally the early migrants that I hear in my recordings= in August are largely American Redstarts and Yellow Warblers. But those I = heard this week were a wide variety=0A= of warbler species.
