Observe newly hatched Gentoo chicks, year-old King Penguin young, and three other penguin species. The Antarctic Convergence creates the planet's largest marine buffet, attracting Arctic Terns migrating over 20,000 miles and humpback whales from Brazil to feast on krill.

Start the New Year with a resolution: start birding! If you can’t tell a sparrow from a flycatcher from a wren, this trip is for you! Instead of racking up species, we will slow down and take more time with each bird, learning how to tell them apart. We'll bring a scope, so you’ll get a good look at each bird's distinguishing features. This is a 2.0-mile walk, with no elevation gain, on an easy trail. Meet in the ABDNHA parking lot by 7:50 a.m. Bring snacks, binoculars, and water. No charge. Register at the Nature Center or 760-767-3098. Max 10.
