Today’s The New York Times has an article in the Science section about “The Grackle’s Secret to Success” here, including a short video of the experiments. It seems that many parts of earth have their own variety of Grackle. And some of them are causing lots of problems for cattle and dairy farms. The particular bird causing problems for the USA is the great-tailed bird, native to Central America.
Over the past century or so the bird has spread north and its range is still expanding, particularly in the West, where it haunts cattle feed lots and big dairy farms.
Looks like we need a bird wall. Anyway, the article says the birds look smart, but the experiments that were conducted with the birds seemed to prove otherwise.
In the desert areas of Israel and Jordan the Grackle is known as Tristram’s Grackle, named for Henry B. Tristram who wrote The Natural History of the Bible in 1868, and numerous other books about the Bible Lands. I am intrigued by the bird every time I visit Masada, along the shore of the Dead Sea. This black bird with some distinctive orange feathers is known as Tristram’s Grackle, or Tristram’s Starling, and is easy to photograph. They like to pose.
