Day 13: Cute chicks

First Cassin's auklet chick weighed today! Once chicks are left alone by their parents, usually after about 10 days, some of them are weighed every five days so we can document how quickly they are developing. This tells us about their health and also about how much food is available for their parents to bring back to the colony. In years when food is scarce, chicks are underweight and slow growing. Jen was pretty happy to be able to hold her first Cassin's chick here. This guy weighed in at a healthy 58 grams.
