Prairie Chickens Part 6 – Chicks

Posted by in Animal Origins & Fun Facts,Endangered Species,Featured

The Houston Zoo raises Attwater’s Prairie Chickens as part of a captive breeding program.  The Attwater’s Prairie Chicken chicks are hand raised and, when they are old enough, many are released into the wild, while others will become part of the breeding program. Chicks begin hatching in late April and the last chicks will hatch in early June. 

Attwater’s chicks are precocial, meaning they have feathers and can move and eat on their own.  In the wild, the chicks rely on the hen to provide heat.  When we hand raise the chicks, we provide them with a heat source and plenty of food and water.  Their diet is carefully measured to maintain the proper balance of vitamins, proteins, and other nutrients so the chicks can grow at the proper rate.  It is important that the chicks are healthy and strong, so that when they are released into the wild they have a good chance of survival.

Devoted Frog Moms

Marsupial Frog

With Mother’s day fast approaching I thought I would stay within the theme and spotlight some frog Moms that deserve recognition.  Warning – don’t try any of these mothering techniques at home!

Frogs can lay thousands of eggs; most species lay them and leave them for natural selection to take its course.  But there are a few dedicated mothers that take great care in keeping their eggs safe.  The marsupial frog keeps her eggs in a pouch. When the eggs hatch into tadpoles, she opens the pouch with her toes. A Surinam toad carries her young embedded in the skin of her back, where they develop until hatching fully formed.  The gastric brooding frog of Australia swallows her fertilized eggs. The tadpoles remain in her stomach for up to 8 weeks, until finally hopping out of her mouth as little frogs. During the brooding period, gastric secretions cease so that she won’t digest her own offspring.  What a frog Mom won’t do for her offspring!

RARE

Posted by in Animal Origins & Fun Facts,Endangered Species,Featured,What You Can Do

Friend of the Houston Zoo and National Geographic Photographer Joel Sartore was recently interviewed on CNN to discuss his new book RARE: Portraits of America’s Endangered Species. View the interview at : http://www.cnn.com/2010/US/04/24/mears.sartore.qanda/

Rare: Portraits of America’s Endangered Species by National Geographic photographer Joel Sartore features portraits of some of the country’s most endangered creatures from flies to wolves.

Some of them are likely to go extinct without people ever knowing they existed, and the goal of this book is to give them a voice. Part of a multi-year project documenting Earth’s vanishing biodiversity, Rare shows what we stand to lose if we don’t act now.

The good news is that there is still time, and this book highlights what each of us can do to save these unique creatures — and ultimately, ourselves.  Photos of these species and many others — some never before published — highlight what we still have time to save.
