West Nile killed these crows. Non-pesticide solutions manage mosquito populations that carry West Nile by supporting bird and insect species that eat mosquitoes. Read more at the link provided.
Save Arlington Wildlife has been getting a lot of reports of very sick crows in town lately, and they have all passed away before we can do much about it. Most of these crows are dying from West Nile virus, which is also felling a lot of hawks and owls in the area as well (including a baby Cooper's hawk in Arlington). West Nile is transmitted via a mosquito bite to the bird. Humans can get it as well. Here's some things you can do to help:
- After a rain, please empty any puddles that have accrued on your property in stacked tires, left out children toys, pet bowls, etc.
If you have a standing bird bath or leave pans of water out for wildlife during heat waves, please dump the water at dusk every night and at least every other day, swab with white vinegar and rinse well before refilling (the vinegar kills stubborn leftover mosquito eggs). The bonus is standing water overnight also attracts rats so dumping water at night can reduce likelihood of rats visiting or burrowing in your yard.
- If you have a marshy yard and live next to or near one of Arlington's many water bodies, you can consider planting (or buying outdoor potted plants) that attract dragonflies like Black-Eyed Susan, White Yarrow, Swamp/Rose milkweed, and Echinacea as dragonflies are adept mosquito predators.
- Also, if you live right next to or near one of Arlington's ponds, consider getting a "Slot Box" swallow nest box on your property next season. Tree Swallows eat a lot of mosquitoes--but they have lost a lot of the mature trees that serve as their critical nesting habitat and their numbers in Arlington have decreased considerably in recent years as a result. This means more mosquitoes and more West Nile mortalities of crows and raptors in our town. Save Arlington Wildlife is glad to collaborate on that with anyone potentially interested and is hoping to get a grant for this purpose.
- If you want to take bird habitat offerings even farther, consider setting up a "dummy chimney" on your rooftop to attract Chimney Swifts--who also are big bug eaters but have lost a lot of habitat.
