Hi Carolinabirders,
Floridabirds listserv has a report of a Ruddy Quail-Dove in Fort
Lauderdale. Seen Friday but apparently not since, but having chased a few
other rarities there (Key West Quail-Dove, Bahama Mockingbird,
Bananaquit) I can tell you that the shrubbery is insanely, impenetrably
dense, so a skulking, ground-hugging bird like that could stay for weeks
without being seen. Just in case anyone happens to be heading in that
direction. Me, I think I'm stuck in NC until March. Maybe it'll stick
around until then...
Speaking of staying at home, saw on the BirdSource website that the Great
Backyard Bird Count is one month away, February 15-18. I probably won't
make a big an effort as usual; not only does my new yard have many fewer
species and individuals than my old one, my new house doesn't have the
big windows viewing the backyard either. But if the weather's nice, maybe
I'll set up a chair and read about nonparametric statistics on the deck
that weekend. Or maybe I'll arbitrarily adopt an honorary backyard
someplace; that's allowed, as long as nobody else adopts the same spot.

I was charged by a Ruffed Grouse in the Hubbard Brook Experimental Forest
in New Hampshire about ten years ago. It had chicks nearby; I actually
saw the chicks first, but couldn't figure out what species of bird they
were until the adult attacked. The chicks could fly several meters,
despite being a fraction (maybe one-fifth or less) the apparent size of
the adult.

The obvious exception to Donna's rule is, of course, Salmonella. It's a
harmless gut bacterium if you're a bird, turtle, or lizard. If you're
human, it's a potentially dangerous infection. So take her advice, wash
your hands frequently and your feeders regularly.

Anyone who agrees with Jack's argument against hand-feeding should not
just avoid hand-feeding. You should avoid feeding wildlife, period. And
that's not necessarily a bad thing. As Craig replied, feeding from the
hand is only slightly beyond feeding from a feeder, or even from the
ground near a house. And in some ways, hand-feeding is better than a
feeder; don't know about you guys, but I wash my hands much more often
than I do my feeders.

I think Craig's hit the nail on the head here by adding "for me". We all
have to remember, when it comes to bird feeding - by hand or in a feeder
- we should not fool ourselves and think we're helping the birds. It does
NOT help, and under certain conditions, it can even hurt. Feeders only
help birds in the most extreme circumstances, such as during sudden
freezes in normally mild climes. Note, for example, how rarely that
Broad-tailed Hummingbird near Greensboro came to its feeder, except
during cold snaps. And we've all heard the statistics on how frequently
hummers need to eat to survive.
The rest of the time, birds are perfectly capable of feeding themselves
with or without feeders. The distributions of birds as we know them today
has been shaped by centuries of selection in a feederless world. Feeders
concentrate birds at densities that are unnatural for most species,
making them more subject to diseases and predators than they would be
otherwise. Also, many species that might otherwise be limited in
population by their food supplies, such as Raccoons and squirrels, can
beef up by raiding feeders (as well as compost heaps and unsecured
garbage cans) and reproduce more. These animals also raid bird nests,
but are not limited by them because of their many other food sources; so
no matter how far the birds decline in abundance, the nest robbers can
keep increasing in number. This may also apply to Brown-headed Cowbirds,
House Sparrows, Starlings...
So why feed? For us. It keeps us in touch with nature, a practice that
has been scientifically linked to psychological health. It gives us
friends to keep us company. It attracts rarities to places where we can
chase them. It gives us markers to tell the passing of the seasons: the
first Ruby-throated Hummingbird of spring, the first Indigo Bunting of
summer, the first Brown Creeper of fall, the first Fox Sparrow of winter.
It bonds us to our environment, which then leads us to care about much
less immediately tangible issues that are much more likely to harm us,
like endangered species, exotic species, global warming, pollution, and
so on. And - most important of all, in my opinion - it inspires many
people to care about wildlife and the environment who would not otherwise
do so.
Feeding birds is not necessary for people to enjoy any of those benefits,
but it does help.

Okay Craig, now you're sounding like a Quaker...
