New video on rescued cormorant chicks & eggs

After being plucked from a huge utility towers in the South San Francisco Bay, double-crested cormorant chicks are being reared and eggs incubated at IBRRC’s bird center in Northern California.

This is the second time we have raised and rehabilitated baby cormorants from eggs. Last year, we raised a small batch of cormorants and had about a 60 percent release rate of wild, healthy juvenile cormorants.

One of our longtime volunteers, Jean, shot this video. Here’s her description:

In the beginning of the video, you can see our large egg incubator. Next you see the youngest chicks, several days old, being fed in an incubator in our ICU unit. They are born naked and blind, but now their eyes are beginning to open. To avoid habituation with humans, we put on a black cape before we feed the chicks. As the one behind the camera, I am also wearing a cape.

The next video clips show increasingly older chicks. The oldest ones in this video were taken from an outdoor cage in a special section of our Pelican Aviary to one of the inside cages, where they will spend the night.

Rescued cormorant eggs get a chance at life

When the guano droppings from the Double-Crested Cormorants nesting on electric towers began to cause problems for the local utility in the South Bay region of San Francisco Bay, it had to take action to repair the damage. Unfortunately it had to remove some of the nests and eggs to prevent further damage to the electrical infrastructure.

IBRRC was called in to help take care of the birds and is now incubating eggs and rearing some of the cormorant chicks that came from these 5 or 6 towers. So far 30 have hatched.

Plans are now in place to prevent the birds from nesting on the towers in the future so this will not occur again.

In the mean time we are posting pictures of the birds as they grow from egg to adulthood and are released. This is the second time we have raised and rehabilitated baby cormorants from eggs. Last year we raised a small batch of cormorants and had about a 60% release rate of wild, healthy juvenile cormorants.

Follow their growth and rehabilitation with us. See the original posting with more photos on our Facebook site

When hazing birds doesn’t go well

Keeping birds out of places we humans don’t want them to be has always been an inexact science.

No more than these pictures demonstrate from Valdez, Alaska where a owl decoy is supposed to be keeping Arctic Terns away from a entrance to a boat dock area.

Notice the eggs in the second picture. NOT exactly working!

These pictures are from Jay Holcomb, IBRRC’s Executive Director, who is in Valdez this week working on a big oil spill drill with bird rescue’s Alaska representative, Barbara Callahan.

However, bird hazing is serious business in oil spill response. So much so that the Office of Spill Prevention and Response (OSPR) and the California Department of Fish and Game came out last year with a Bird Hazing Manual: Techniques and Strategies for Dispersing Birds from Spill Sites.
