Day 59: Chicklets

Pigeon Guillemot chicks are hatching. This is one of our followed sites that has two fresh chicks. PIGU chicks, like Rhinos and Casssin's Auklet chicks, get weighed every 5 days so we can track their development. Because the eggs typically hatch a few days apart, the fist chicks to hatch can often be much larger than its younger sibling. If the younger sibling can survive until the first chicks fledges, it will often gain weight rapidly to make up for lost time.
