Hi Carolinabirders,
I would hesitate before celebrating the "adaptation" of Pileateds to new
environments. We discussed here a while back about Wood Thrushes, and how
"source" populations of successfully breeding birds could supply
individuals to "sink" populations where the birds could survive, but not
reproduce. As large areas of the eastern US revert from farmland to
forest, most of the region is reporting declining populations of species
like Grasshopper Sparrow, which benefited from all the agriculture. It's
only natural that as Grasshopper Sparrows decline, Pileated Woodpeckers
increase (at least until the habitat gets turned into housing
developments and shopping malls and they both disappear).
This rash of suburban Pileateds may just be, as Charlie Thomas suggested,
mostly young birds which lose competion with older birds for prime
territory in the forest, and are forced out into the suburbs. While Rob
G. found a family which successfully raised young, most residential
neighborhoods are too paranoid about hurricane damage and immediately
remove any large limb, if not entire tree, which shows even the slightest
sign of decay. With no decaying wood, the Pileateds have nowhere to nest,
and can only feed and survive and hope that a better habitat opens up
elsewhere.
Or maybe I'm just jealous. I live on the edge of the Duke Forest, which
you might expect to predispose me to have Pileateds in the neighborhood.
However, after nearly a year in this location, I have not even heard one,
much less seen one. Much of the adjacent woods is dominated by young
trees, so either it was farmland too recently, or the DF has too short a
cutting rotation to support Pileateds.
I mentioned here a while back about "The Race for the Rainforest", a
web-site which arranged for donations of money to the Nature Conservancy
for rainforest preservation every time you clicked on the right button at
the site. Well, I just noticed that there is now a second site doing the
same thing! This one is a spin-off of "The Hunger Site", and donates to
TNC's "Adopt an Acre" program. You can get there directly at
http://www.therainforestsite.com/, or from The Hunger Site via an icon at
the top of the page. Happy clicking!
And if anyone is on the Outer Banks this weekend and sees a gang of
birders from Massachusetts, tell Bill and/or Barbara Drummond (Bill
should be on pelagics tomorrow and Sunday, Barbara usually stays on land)
I said hello...
