For the first time in at least 20 years, herons have built their nests at Marymoor Park in Redmond. John Reinke watched the herons as they built the nests and raised their young, documenting the events with his camera.

The nests are in cottonwood trees near the off-leash dog area. It's enclosed by an orange plastic hazard fence to keep dogs and humans out of the area underneath the nests.

Parents feed their young by regurgitation. Reike says one can easily tell when a parent has arrived back at the nest by the loud croaking and cackling noises made by the youngsters as they compete for food.

Reinke says according to signs posted at the site, all of the young herons will be fully fledged (able to fend for themselves) by the end of July, so there's still time for folks to go out there and have a look.
