If you guessed black-necked stilt, you're correct. It's certainly an appropriate name, with the black neck and stilt-like legs. A couple killdeer were following it around, providing some good spring entertainment.
One of the best places to observe spring migration is Fish Springs National Wildlife Refuge. The oasis attracts thousands of birds, providing an important feeding ground on their migration. It's also fun to see what pops up in the backyard. I always like to think about where the migrating birds have come and where they're going--it's a bit like being an armchair traveler, with different birds inspiring thoughts about different trips.
