SeaWorld San Antonio penguin population has increased with the recent hatching of Chinstrap
Penguin chicks. http://www.seaworldsanantonio.com/sanantonio/default.aspx
This has been the most successful year for Chinstrap
Penguins in SeaWorld San Antonio’s history, with nine chicks produced.
Chinstrap Penguin chicks average about 70 grams (about 2.5 oz.) when
hatched, but easily grow to over 500 grams (a little over 1 lb.) in just ten
days, thanks to the regurgitated fish fed to them by both parents. They will
get their distinctive black “chinstrap,” along with their other adult
feathers, when they fledge at about three months of age.
