<div dir="auto">Thank you Kathy! Point well taken! All members of the crow family - including jays and magpies are well known nest robbers, taken eggs and young of other birds. I have even seen them take small Mallard ducklings. With the noticeable increase

Another possibility for lower small bird numbers is the large number of crows who spread out from the communal roosts to breed in neighborhoods throughout the county. I have seen crows eat or kill nestlings and other birds and carrying nestlings, to their
offspring I guess. <br>
