The Black Bird Invasion

Grackles and Starlings over UTMB at Dusk.jpg 

Every year the University of Texas Medical Branch (UTMB) in Galveston, along with other sites throughout the island, is hit with a blizzard of black birds, mostly Great-tailed Grackles mixed with European Starlings. During the day the birds are not very noticeable, just part of the local avian life. But at dawn and at dusk, they congregate to roost in trees and on ledges, filling the dim sky with the din of their cry and the muted flutter of hundreds, perhaps thousands, of wings. I need not go into detail about the side effect of these roosts upon the sidewalks and lawns under the trees.

These nocturnal deposits have led many residents to attempt multiple strategies to convince the roosting birds to find a new set of trees for their bedroom. We have had plastic owls with mechanically rotating heads, tapes of hawks and other raptors, booms and bangs of recorded fireworks and shotguns, but none of them seem to have a long term impact. The grackles, after all, were roosting here long before we arrived, and behave as though they have the right to continue regardless of what we may think of them. The starlings have joined the grackles over the last century but seem to be equally assured of their property rights. I like to point out to those who complain about the grackle/starling invasion that the primary food of both species when they are here is insects, especially yummy larvae. If we have, say, 200,000 birds in the combined flocks (which is easily imaginable) and they stay for 30 days and eat, on a guess, five insects each every day, then the island has been spared 30,000,000 bugs that would still be around if the flock were to leave. And if that’s not a blessing, I’m not sure what is.

Rembembering the Snow of ‘04

Mockingbird in Snowy Tree on Christmas Morning.jpg 

The new year is upon us and so far the winter weather in Galveston has been erratic but not too bad. According to our local weather guru, we are overdue for a hard freeze. The last time the thermometer hit freezing, and just barely at 32 degrees, was during the great snowfall of Christmas Day, 2004. We had almost four inches of the white stuff and it obliged us by sticking around for three or four hours so we could enjoy it. The photograph here was taken that day and shows our resident mockingbird waiting for his/her daily dose of raisins. I could swear he/she is frowning about the weather, but it’s not clear from this distance.  

That was the second snow of our 20 years here. Snow on palm trees looks a little anachronistic, but interesting. Kids (and their parents) were out in the wee morning hours, building snowmen and making snow angels before the sun would come up and start the thaw. The heaviest snowfall here, six inches, was on January 12, 1886, and it was notable enough to make the New York Times. According to the Times article, by “10 o’clock” the weather moderated enough that “thousands of clerks and others in the business part of the town turned out and enjoyed the novelty of snowballing.” I don’t doubt that the weather was a novelty, but the “thousands of clerks” does somewhat bewilder me. This was a thriving commercial and economic center in 1886, but I doubt that there were that many clerks in a town of just over 22,000. This was probably just a little NY “Yankee” hyperbole.
