Jim Williams has been watching birds and writing about their antics since before "Gilligan's Island" went into reruns. Join him for his unique insights, his everyday adventures and an open conversation about the birds in your back yard and beyond.
This morning's (Wednesday) birding column in the StarTribune (Variety section, Home and Garden pages) talks about the impact this summer of black flies on Common Loons and other birds. I do not mention Osprey in the column, my oversight. Once I thought to ask the question, this is the reply I received from Judy England, who keeps track of nesting Osprey in the metro area:
"Yes, black flies are terrible on Ospreys this year. Both the male and female from the nest on webcam at the Arboretum left the single chick alone Saturday night for over one-half hour, just before dusk. The chick was so agitated by the flies that it edged itself over the side of the nest and died. I am watching the black flies crawl all over the adults through my scope when checking osprey nests, and their head-shaking does not cease. Chicks are also crawling under the wings of their parents to escape the insects. (Shaded chicks would simply sit in the shade of the adults.) Historically, they would have gotten a little reprieve in the evenings, but the mosquitoes are so horrible they are not getting a break this year."
REPORT NESTS: This note comes from the Twin Cities Osprey Watch
We have had many osprey nests fail this year and adults have left their nests. They often build "frustration nests" after a failure. I am requesting that anyone who sees new nests popping up, or adult ospreys carrying sticks in the eight-county metro area, to please report this activity to Twin Cities Metro Osprey Watch so we can identify these birds and locate new nest sites as part of our ongoing research. Please contact us at firstname.lastname@example.org
We also have a Facebook page for more Info about metro ospreys:
