The Raptor Cam Red-tail nestlings are now 7, 7, and 4 days old respectively. The older nestlings have completed there first week out of the egg. To put into perspective how fast they are developing at this point, they are already more than 1/7th of the way toward flying. They have a thick layer of downy feathers and are increasingly able to keep themselves warm. There are already longer and longer periods where the parents are not brooding them (but are always close by). often when the parents are not visible in the nest you can see their shadows as they perch on the railing above. The nestlings  vision is becoming more acute.

The fourth egg still has not hatched but don't give up hope yet. It is still possible but with each passing day it becomes less likely. If it does hatch at this point, the nestling will be significantly behind its siblings and it will have tough road to travel. When we had an unhatched egg in 2009, this pair of red-tails has left the unhatched eggs in the nest with their young. Kind of like the plastic bags that this pair also leave in their nest, the unhatched egg would  periodically appear and disappear among the branches and greenery of the nest. and the young would play with it.. You can get a sense of how much the young have grown already by comparing them to the unhatched eggs--just a week ago they would have fit inside!

Right now it is still pretty much impossible to determine the gender of the nestlings. Over the next ten days or so it should become a lot clearer. The females are bigger than the males and you can usually begin to see a difference as they get towards the end of their second week.

AUDUBON WILDLIFE CARE CENTER ON-LINE AUCTION.

If you would like to support Raptor Cam and want to have some really cool experiences, check out the Portland Audubon Wildlife Care Center On-line Auction. Each year we auction off unique experiences to support the operations of our wildlife hospital. These experiences range from climbing an old growth Douglas fir with professional climbers to a behind the scenes tour of the Oregon Zoo Condor Facility to soaring like a hawk in a glider. I am offering the opportunity to come along on a peregrine falcon banding trip-an experience that will give you an up close view of the fastest bird in the world nesting right here in the middle of Portland. The proceeds help support Audubon's Wildlife Care Center---a facility that takes in over 3,000 injured and orphaned wild animals each year. In past years several of our raptor cam fledglings have spent some time there are running into window and cars. The Care Center is completely donation funded! Check out the auction!
