Hi John et al, Thanks for your post. I think goshawks probably have the highest % of mammals in their diet of any accipiter. I did some reading and, interestingly, a study in NY found that their two most common food items were red squirrels and crows. Guess what the two most common predators

Ms. Molison, Pesticide use is a serious matter, whenever, wherever. However, the material used for the recent mosquito spraying in FC (resmethrin), and the manner in which it was applied (fogging at night), make it very unlikely this is the cause of House Finch deaths observed by Mary France

Grandview Cemetery in Fort Collins (Larimer) is lush at present, like most of the Front Range. The recent rains are responsible, as they were for a true happening this evening. Soft soil in late summer often triggers mass emergence of the winged stages of ants (female queens and males).
