Bird festivals have become increasingly popular in Washington, a chance to mingle with experts, see birds that can be added to your life list and get outside after this winter’s challenging weather.

One of the most jam-packed festivals is the Sandhill Crane Festival, a great gathering that gives folks a look at the cranes, which don’t spend much time in Western Washington, as a choice of birding-related events March 23-25.

Warning: If you’re interested, go now to www.othellosandhill.com

cranefestival.org. Some of the outings are already full. Fortunately, there are dozens of choices, many of them taking place in the Columbia National Refuge Headquarters near Othello.

Here is a sampling of the guided tour options that might still be available:

– Bike for Cranes. Pedal through some of the best wildlife viewing areas on a 20- to 25-mile ride on flat and rolling terrain.

– Potholes. A seven-hour birding expedition to the shrub-steppe and wetlands of the desert wildlife areas. Expect raptors, and possibly snowy owls and Say’s phoebe. There’s also a Potholes Reservoir birding-by-boat trip.

– Take refuge. Take a six-hour birding tour of the Columbia National Wildlife Refuge.

– Cranes and owls. Check out the sandhill cranes and burrowing owls.

– Don’t forget. The Forgotten Trails tour follows an ancient path with historical and geological interest.

– Drumheller Channels. Learn about the geological features and history of channels created by the Missoula Floods.

– Get squirrelly. Take a two-hour outing to a colony of ground squirrels.

– Wahluke Slope. Birders visit the slope, Hanford Reach National Monument and Saddle Mountain National Wildlife Refuge.

– Wet and dry. Both habitats will be explored on this all-day trip to the Sun Lakes.

– Lower Crab Creek. The trip concentrates on the Russian olive groves and wetlands of this wildlife area, the cliffs of Saddle Mountain, and wetlands where the cranes roost.

There also are dozens of lectures and workshops led by experts, including “The Lives of Dragonflies,” “Owls of Eastern Washington,” “Bats Life in the Dark,” “Birds, Bats and (Windmill) Blades,” “Bhutan: Tiny Gem with Tremendous Value,” “Crane Festival Photography Workshop,” “Insects for Kids,” “Dead Wood and Wildlife” and “Butterflies of the Basin.”

Other birding festivals include:

Emphasis is on birdwatching in the quiet bays, estuaries and beaches; a five-mile-long sand spit; and the Dungeness River Valley in search of marbled murrelets, rhinoceros auklets, peregrine falcons, pygmy owls and others. There’s also a Protection Island boat trip. Information: www.olympicbirdfest.org.
