Hi Helen,
=20
The first breeding song birds can move out of Nova Scotia as early as =
late July. Historically there have always been early pulses of migrant =
song birds so the birds James is seeing and the birds John Kearney is =
detecting at this time of year are not unusual. In fact, sightings of =
birds congregating at this time of year can also be pre-migration =
gatherings rather than birds actually leaving Nova Scotia . While =
shorebird migration peaks in July, passerine migration won=E2=80=99t get =
going in earnest for another couple of weeks.
=20
As James=E2=80=99s sighting suggests, the various species of flycatchers =
are some of the first song birds to head south.
=20
Sightings of vagrants will start to pick up now as a result of post =
breeding dispersal, of some young birds migrating incorrectly and of =
weather systems pushing birds to unexpected locations.
=20
Cheers,

Would these migration times be earlier than normal or about normal?

I had my first warbler wave move through the yard this morning in =

migrating birds moving through there also.

Last night I took a drive to Broad Cove. I watched two juvenile bank =
swallows being fed by adults on the wires beside the road. Interesting =
was that two or three yellow-rumped warbler juveniles and barn swallow =
juveniles and black-capped chickadee juveniles kept landing beside the =
juvenile bank swallows and sometimes crowded them to the point of making =
them move. I got the impression that they were looking for free =
handouts from the adults bank swallows when they came in to feed the =
young. I've never seen this activity before.

The eastern bluebirds in Back Cornwall I was told as of today moved out =
a week ago. =20

I never posted it as they did not stick around, but about a week ago, =
Lise Bell had two juvenile yellow-crowned night herons on Bush Island. =20
