Athena the owl is back at the Lady Bird Johnson Wildflower Center, having laid an egg for the 16th consecutive year.

Two condors in far northwestern California appear to be caring for a recently laid egg, a historic moment in an effort to bring the massive raptors back to the Yurok Tribe's historic homeland.

Kakapos, which are reclusive and flightless and can live as long as humans, are found only in New Zealand. They feed on the fruit of the rimu tree.

Biologists in northern California believe they have spotted an egg in a condor nest in an old-growth redwood, the first such discovery in 100 years.
