So you take the temporary trail behind maintenance and then take the temporary loop. At the end take the little footpath down past two small logs and two large logs that cross the foot path.
At the third log stop and turn left and the bird is right there.
And it was.
Yellow-Billed Cuckoos don’t lay their eggs all at once: the period between one egg to the next can stretch to as long as five days. This “asynchronous” egg laying means the oldest chick can be close to leaving the nest when the youngest is just hatching. When food is in short supply the male may remove the youngest bird from the nest, though unlike their relative the Greater Roadrunner, they don’t feed them to the older siblings.
