Tucson, AZ, United States
A pair of roadrunners built a nest in our yard and I observed the entire process from nest building to raising and feeding the young. Five babies successfully fledged. Both parents tirelessly brought in lizards to feed the chicks. Lots of lizards. This is a Whiptail Lizard – and yes, the chicks swallow it whole, always head first, and the tail may stick out of the bill for awhile until the front part of the lizard digests.
