I've seen two Killdeer around the pond since early June. I wonder if they're are pair or siblings?
If they are a pair, wonder where the nest is?
The pond and it's environs are full of questions that I ask myself every day!
Green Herons nest in trees and shrubs near water, or dry woods and orchards as long as it provides seclusion and there is water nearby for foraging fish or frogs.
Last year we saw a Green Heron Butorides virescens several times here on the pond shore, hunting for a meal. To see those previous photos and information about how these birds use tools to hunt, enter heron in the search box at top left then press return.
