[SBB] FYI -- Swallows nesting earlier

["Chuq Von Rospach" <[[email protected]]>]

Ron Thorn mentioned on the lists earlier this week he's seeing
pelicans in numbers he normally wouldn't.

I thought about that when I ran across this today. Out of New
Scientist, a report that barn swallows are adapting to the change in
climate by nesting earlier to give them more time to take care of
their first brood before their second nesting....

Warmer spring temperatures and a longer growing season are proving to
be good news for barn swallows. Over the past 35 years these birds
have responded to global warming by taking more time over rearing
their chicks.

Around two-thirds of swallows produce two broods of chicks per year,
one in April and another in July or August. Anders Møller from the
Pierre and Marie Curie University in Paris has monitored barn swallows
in the Kraghede region of northern Denmark since 1971, noting the date
eggs were laid, and clutch and brood size.
