[Tweeters] Seattle’s Adaptable Urban Cooper’s Hawks – Thursday Nov 9 7 pm via Zoom or in-person

[Dennis Paulson]

If we’re going in that direction, I suggest we resurrect “Pigeon Hawk” for this species, taking it away from its former use for the Merlin. I have actually photographed them taking four Band-tailed Pigeons in our yard, and I presume those weren’t the only ones. I know pigeons and doves are very important components of their diet in some areas. I’ll admit that as a person who admires hawks but who also cherishes the abundance and diversity of birds at our feeders, I have mixed feelings about them becoming more and more common.

In the Cooper’s Hawk account in Birds of the World, it mentions one nest at which 66 robin-sized prey items were required to raise a single young to age 6 weeks. Three young x 66 = 198 such prey items taken in the area around one nest in one breeding season, although that’s over a fairly large area. And I can’t say I’ve seen any decline of pigeons or other birds of that size in my yard, so presumably that level of predation doesn’t represent a problem for local bird populations.

It does have the local effect of emptying our yard completely of birds when a Cooper’s Hawk comes through, sometimes for several hours. Those smaller birds know how to play it safe.

>> Thirty years ago, Cooper’s Hawks began colonizing urban and suburban landscapes throughout the US, developing a tolerance for living near humans. Ed Deal, from Seattle’s Urban Raptor Conservancy, will provide insights into these birds. Since 2012 the group has monitored the hawk’s nesting density and productivity; the population has nearly tripled in just 12 years.  Please join us to learn about the hawk, their nest site fidelity, migration and dispersal patterns as well as the protocols used for the study.  This free program from Black Hills Audubon Society requires registration at:

>> You can also join us in person at Temple Beth Hatfiloh at 201 8th Ave SE, Olympia where there will be refreshments and social time at 6:30.  Ed will be speaking live from the Temple.
