It’s a good thing we have had lots of practice with the larger birds. The smaller herons are moving in now and they have very different speed.
This species of Night Heron is about 2 foot (61 cm) tall and stocky. They feed mostly at night but during breeding season they are out with everyone else. They tend to chase each other, all the time.
The trick to catching an in flight shot with these is to have enough open space to follow their flight as the zoom by. Focus on the first images is usually not good, I need to catch up with them.
