In April 2011, I once again arrived on the Farallon National Wildlife Refuge to start another season of seabird research working with PRBO Conservation Science. In my seventh and perhaps last season, I decided to start a photo a day challenge for myself. The challenge is to share a new and interesting photo for each day I am on the island this year.
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.
