Annual Bird-a-Thon 
Saturday May 15, 2020 
This year we will still try to find as many different species as possible in a single day. However, we won’t be doing it in groups. We will be looking for birds, as individuals, not in groups. You can help by birding your local park, or you can  pledge a donation based on the number of species we find. Pledge today. Pledges can be a flat amount such as $25.00, or you can pledge a given amount per species such as 25 cents per species. Then, if we see 120 species, your pledge will come to $30.00. Thanks for your generous support! Remember, even if you’re not participating, please pledge to the Bird-a-thon to make our efforts worth it and support Hudson River Audubon. Contact Michael Bochnik if you would like to help count birds

 ___ I am happy to pledge $ _________ per species in support of your bird-a-thon.
