New Scientific Paper Printed: Caspian Terns Saved, Rehabilitated, and Launched by Worldwide Chicken Rescue Are Surviving and Breeding!
Chicken Rescue is proud to announce the publication of an essential scientific paper on a rescue-and-rehabilitation effort that led to a notable success: the post-release survival and breeding of a bunch of Caspian Terns in Southern California.
The paper was revealed in 2020 Bulletin of the Southern California Academy of Sciences.
The story started in 2006 and 2007 within the Port of Lengthy Seaside, one of many busiest transport ports on the west coast and close to a well-liked breeding colony locale for each Caspian and Elegant Terns in southern California. In each years, disastrous occasions threatened the lives of tern chicks born within the Port of Lengthy Seaside.
In 2006, employees cleansing the deck of a barge intentionally flushed Caspian Tern chicks—too younger to outlive independently—into the Pacific Ocean. In 2007, suspected human disturbances prompted one other group of tern chicks to wind up floundering within the water. Luckily, Chicken Rescue was capable of rescue a few of these younger birds and take them into care at its Los Angeles Wildlife Middle.

The truth that these chicks had been capable of survive and breed after launch is very noteworthy as a result of terns pose distinctive challenges for rehabilitators. Grownup terns usually nest in colonies and are plunge-divers, which suggests they elevate their younger communally and so they hunt by hovering over the water in flight, recognizing fish under the floor, after which plunging into the water to catch their prey. Changing into efficient at feeding on this vogue requires coaching and observe, so younger terns spend many months flying with and being guided and supplementally fed by their dad and mom to grasp this talent nicely sufficient to outlive on their very own. Sadly, the sort of studying is just about unattainable to duplicate in captivity. Conservation efforts that work nicely with different species of birds, corresponding to captive rearing for wild launch, will not be appropriate for terns. And the state of affairs is made extra determined by the truth that critically endangered tern species inhabitants numbers proceed to drop: tern colonies stay weak to environmental disasters and human disturbances that disrupt breeding for a whole colony, or kill all of its younger of the 12 months without delay.

Chicken Rescue pioneered a novel, “pure” technique for turning the rescued chicks into succesful, self-sufficient grownup terns. The truth that a number of the rescued chicks have been seen as adults, alive and in breeding colonies years later, is a powerful signal of the hassle’s success. With Chicken Rescue’s care and assist, these chicks overcame their traumatic youth. These very younger birds realized to fend for themselves and survive, and had been capable of breed efficiently as adults. This validates the care routine at Chicken Rescue and provides us hope for future populations.
As rehabilitators, we really feel proud understanding that our in depth rehabilitation efforts had been a hit. We additionally need to acknowledge the knowledgeable collaborative assist we obtained from ornithologist Dr. Charlie Collins, Professor Emeritus at California State College of Lengthy Seaside.
