Nancy,

I did check weather systems in late February and nothing seemed apparent =
to me to explain Black-crowned Night Heron.

Thanks so much for providing these analyses. It really explains the =

that one.=20

=20

Did you notice any strong weather systems that may have carried it in =
Feb? I see McLaren records one having survived on CSI =E2=80=9Cuntil at =
least late February=E2=80=9D in 2000 (All the Birds of Nova Scotia). You =
have to wonder if one overwintered on Bob Portage or somewhere N of the =
main wintering range and was possibly displaced further north at some =
point (total speculation on my part).=20

Hi Rick and all,

That=E2=80=99s an interesting comment about how the arrival of herons =
and egrets in March were similar to what one can see with a hurricane. I =
just finished checking the weather systems in March, and there were two =
that could have brought migrating egrets/herons to Nova Scotia. Both =
systems had an =E2=80=9Ceye=E2=80=9D with calm winds at surface levels. =
The first one would have picked up birds off the southeast coast of the =
United States on the morning of March 12. If the birds were able to keep =
up with the speed of the eye, they would have been deposited in =
Shelburne County on March 14 at 6:00 am (42 to 48 hours in flight). The =
second low formed on the morning of March 21 off North Carolina but did =
not form a typical eye. Rather there was a long tongue of calm weather =
sandwiched between opposing high winds with the tongue extending out in =
the Atlantic south of Nova Scotia. This tongue eventually twisted =
northward and would have deposited birds just east of Halifax at about =
3:00 PM on 22 March (about 32 hours in flight). If this analysis is =
correct, the birds would not have received any wind assistance in flying =
such a distance. But herons and egrets are good gliders, and this might =
explain their ability to keep up with the eye/tongue in near calm winds.

The Black-crowned Night Heron on March 1 doesn=E2=80=99t fit into either =
of these scenarios.

Just to add to Wayne's comments about carriage of these herons by major =
air movements, if you check eBird today, March 31, the most northerly =
Little Blue Heron in the eastern US is in Connecticut, seen yesterday. =
The second most northerly is in New Jersey, also seen yesterday. (These =
would be "approved" reports.)

=20

The most northerly Tricolored Herons in the eastern US are also in New =
Jersey, about seven birds seen Mar 29-31.

=20

Both species will eventually reach sw Maine or n Mass. as the limits of =
their breeding range, so these birds in the US are still heading N under =
normal migration patterns. The transfer that occurred a week or so ago =
was pretty much similar to what happens during hurricanes.

Hello Nancy,

This and the other egrets found more recently in NS are likely carried =
here from the Middle Atlantic States by the massive movements of air =
associated with storms.  Most of the 12-15 in NS, Newfoundland, and St. =
Pierre seem to have been carried here by a major air movement from North =

Saturday.  I don't know whether you are counting these as first migrants =
