I just fin= ished checking the weather systems in March, and there were two that could h= ave 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 p= icked up birds off the southeast coast of the United States on the morning o= f March 12. If the birds were able to keep up with the speed of the eye, the= y would have been deposited in Shelburne County on March 14 at 6:00 am (42 t= o 48 hours in flight). The second low formed on the morning of March 21 off N= orth 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 exte= nding out in the Atlantic south of Nova Scotia. This tongue eventually twist= ed 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, t= he birds would not have received any wind assistance in flying such a distan= ce. But herons and egrets are good gliders, and this might explain their abi= lity 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 o= f these scenarios. > John > =20 > From: naturens-owner@chebucto.ns.ca <naturens-owner@chebucto.ns.ca> On Beh= alf Of Rick Whitman > Sent: Saturday, March 31, 2018 20:15 > To: naturens <naturens@chebucto.ns.ca> > Subject: Re: [NatureNS] Super early BC Night Heron > =20 > Just to add to Wayne's comments about carriage of these herons by major ai= r movements, if you check eBird today, March 31, the most northerly Little B= lue Heron in the eastern US is in Connecticut, seen yesterday.
