Just a few weeks past the solstice, and the real heat of summer is yet to come. Some shorebirds are already on their way south, but most songbirds will be here for a while longer. What's the best time of day to look for them? Many birds are most active in the early morning, taking advantage of the abundance of insects at that hour. Midday heat sends people inside, and birds take a siesta, too. And then, both birds and bugs rev up again in the late afternoon.
