Subject: Re: [VTBIRD] Boblink weather event?
Agree, Ted.  In the grand scheme of Bobolink population dynamics, this is a minute event.
Went out to Catamount this morning. Not a Bobolink to be seen or heard.  The distressed pair we saw Monday must have pulled up stakes. Plenty of Song Sparrows, Common Yellowthroats and Redwings (including fledglings)  in and around the field, so other species seem to have been unaffected by the weather events.  Which leaves me with this question.  Where do the adult Bobolinks go after nest failure at this stage?  Do they hang around Vermont where there is plenty to eat, or do they head south early?

Again, thanks to all for your interest and contributions to this discussion.

Sarah, Carl, Eve,

Remember that bobolinks are birds of the tallgrass prairies that moved east
as we cut the deciduous woodlands over the past couple of centuries.
Tornados are regular prairie weather events with which bobolinks (and other
grassland birds ) evolved.
