Finding bird nests is something typically reserved for late autumn, when fallen leaves reveal summer’s hidden treasures. But I’ve been lucky this spring. Bluebirds and trees swallows took up residence in nest boxes we put up in April; a robin returned to a nest used last year on an upstairs window ledge; I spied a pair of cardinals making their nest in a hemlock bough; and, just last week, I caught sight of an American redstart as it landed and disappeared into a tangle of shrubbery at the edge of the woods– a tell that led me to discover its well concealed nest. I know there is a lot more nesting going on in the surrounding woods and field, but it may be autumn before I am able to add more to the map.
Tips and Techniques– I love making maps and find that it is an excellent way to learn and record information. I made this one so I would have a reference for future years’ nesting activity on our property. I used Google Maps to sketch the aerial view– it’s a great tool for getting the basics of the landscape geography you want to record. Once I had the map laid out, I added the nest, using a photo of the actual nest so as not to disturb the birds. I had been hoping an egg or two would have already been laid, but because I was a bit too early, I decided to add the eggs for each bird as a separate element. I used the Princeton Field Guide Nest, Eggs, and Nestlings of North American Birds by Paul Baicich and Colin Harrison as a reference, as well as an atypically oblong robin’s egg found abandoned near our driveway.
