Even with the high numbers, it was still difficult to get good pictures as these warblers are typical small birds, constantly moving and never letting you get very close. Just when you think you have a great shot, the bird will fly away just as you push the shutter. It can get frustrating.Then, as I was walking along a trail with tall grasses on either side, I came across a male and female that were feeding along the tops of the grasses near the trail. I was able to get many pictures, some of which turned out pretty good, even with the gloom of the overcast skies.Then, yet another surprise. I saw another Yellow Warbler that looked a little different and was flapping its wings vigorously as it was perched on a stalk. Soon another Yellow Warbler approached and I realized that the first warbler was a fledgling as the adult brought an insect and feed its young.I love watching adults feed their young.
