I just finished up a job at the Calgary Auto Mall. I took out 20 spruce trees in the Ford's dealership complex. Every tree had a minimum of one nest in it. Mostly crow, but with a mix of magpie.
There were four nests that were active. The first was just eggs (easy), but today resulted in three with not yet feathered young ones. Fugly buggers, but still living creatures. They were dispatched as humanely as possible. To be totally honest......it sucked.
What puzzled me was the lack of protective adults, and nest proximety. Just a very weird situation that after 15 years in the business in Calgary I have never experienced.
