1–I have not seen any one legged crows nearby. I have no knowledge of the local impact of West Nile. 2. I have only seen crows cooperating. I did witness several crows trying to get a hawk out of the territory a few years ago. They kept flying into the hawk. After repeated attempts, one of the crows went at the hawk again, there was a tussle, and the crow fell straight down out of the sky. This was taking place at a height above white pines. I realize it’s life in the wild, but it was a little sad and shocking to witness.

1. Possible increased risk for genetic mutations. 2. I was not aware of extra pair fertilization but it appears to be beneficial as a method used to ensure continuation of the species.

I think the strength in numbers works to their benefit here. It’s just a matter of being patient and in the meantime they may learn parenting techniques from helping out that they will also benefit from in the future.

1. I have a family of crows that I have watched in my yard that appear to be teaching the younger generations to forage during the summer. I have seen a flock foraging in corn fields once the crop has been cut in the fall. 2. Last fall while looking for snow geese during their migration and stop over in the Lake Champlain Valley, I witnessed a huge flock of red-winged blackbirds. They literally blackened the sky where they flew. They landed in several large trees that had shed there leaves and filled them. When they were in flight they flew in such tight formation they appeared to be an art form. I also regularly see flocks of Canada geese, cedar waxwings, blue jays, and turkeys, but no where near the size of the crows, snow geese, or red-winged blackbirds.

1. There is a large (tens of thousands) roost in Lebanon, NH. I get to see this in the late fall/winter time. One year they were roosting along an interstate exit ramp where there are only deciduous trees, another year they were roosting on the property of a hospital campus “camping out” in both deciduous and conifer trees. They are an incredible sight. My thought on why these two sites were chosen (within a couple miles of each other) is the benefit of the increased amount of nighttime light they can use to help protect them. In the vicinity there is a city dump, many restaurants with dumpsters, several rivers, a college with lots of pizza, and a lot of open space all of which could be useful to crows. 2. During mid to late afternoon there is a steady stream of crows all flying in the same direction heading to the roost. It seems there is a lot of dynamics being worked out among the roost population with the amount of chatter and jockeying that occurs. Others who have witnessed this have reacted with disgust which seems like an unfortunate disconnect with nature to me. I feel fortunate that I have had the opportunity to witness this crow behavior.

1: I’d let them know we should be more concerned about squirrels and chipmunks in our area. 2: I have had a family of crows in my woods for several years now. I do not know where their nest is...yet. 3. In the part of New Hampshire that I live I generally only see crows. But when I hike in the White Mountains I see and hear ravens. 4: All things are connected. In New England we have a tick problem. Crows that feed on small rodents have the ability to break a link in the web of causation that causes disease in humans. The tick feeds on rodents, among other things, and then feeds on people, causing Lyme and other diseases. The crow is a welcome part of my neighborhood. It is also helpful for the same reason for the deer and moose populations as well as my dogs.
