I did some research and apparently cardinal chicks stay in the nest for 8-12 days, so we are right around half way done with this little experiment. Their feathers are coming in nicely.
first started this little adventure. Its no wonder, as they are fed a lot by their dutiful father.
I have learned that they rouse and wake up just before the parents return to the nest, so the secret of this sort of photography seems to be keep a lazy eye on the camera screen as you go about your day, and when the chicks open their mouths, you have 20-30 seconds to get ready to shoot shots of the parents.
... which is fed to one of the chicks.
That will have to wait until tomorrow. Come back soon to see more pics of the chicks and watch them grow from egg to fledgling. You can see all the posts of the birds by clicking this link: Avian Landlords.
