Desert Tortoise Takes First Drink of Spring

Tortoise hibernation, or winter torpor, is an amazing adaptation. For 3-5 months they sleep without eating, drinking or eliminating waste. When they wake up in the spring, they need a long drink of water.

This male desert tortoise has been hibernating since the first week of December 2016. He woke up this morning March 16, 2017.

Watch him drink. His eyes and nose are submerged. He lets the water bathe his eyes and sucks water in and out of his nasal passage to flush out his nose. The Aldabra tortoise, from islands in the Indian Ocean, is known to have a flap in its nasal passage that allows the tortoise to draw water up its nostrils and into its throat without pulling the water into its lungs. I think there is a good chance that other tortoises have this adaptation as well. If you look closely you can see a brown plume area in front of the desert tortoise's nose where it has pushed away the dirt on the bottom of the pan as it blew water out through its nostrils. 

Notice how much he drinks. How much lower the water level is along his body when he stops drinking. 

The creatures around us have amazing adaptations for survival. Definitely worthy of an extra minute to stop and appreciate.

Autumn in Los Angeles

Yes, southern California has seasons! They are just different from the expected and therefore are typically discounted.

Summer is a time of dormancy for our plants, not winter. Winter is our time of growth and renewal. With recent Fall rain, bulbs are appearing. 

It is also time to plant. Native plants are more likely to be successful if planted in the Autumn. This gives them all winter to establish themselves before the harsh realities of a dry hot summer. We're planting natives that we picked up at the CA Native Plant Society plant sale last weekend.

Sages have been successful for us and they provide nectar for Valley carpenter bees and hummingbirds. We're trying a new Salvia leucophylla. This desert sunflower, Encelia farinosa, is a new species for us. Hopefully its flowers will provide nectar for bees and butterflies (Name this Butterfly). 

Some CA creatures are preparing for a long winter sleep. See more Earth Minutes with desert tortoises:

Creating habitat is a year-round effort, but Autumn in Los Angeles is the time to start something new. Native plants attract wild creatures and bring Earth Minutes to you. More on native plants and native plant gardens.

Desert Tortoise Hibernation

One of our California desert tortoises is having a hard time settling down for the winter.

HD

The weather has been cool and windy. The others are fast asleep, but this old female is still up and about.

What causes desert tortoises to enter winter torpor? The science is still out, but it seems to me that it is not one thing. Yes, cool weather is part of it, but it's been in the low 40 degrees F at night for nearly a week. The days have been windy and typically in the low 60s. Still she slowly wanders out to find a place in the sun.

Low angle sunlight, shortening daylight, cold winds, all of these play a role. Yet, this old girl hasn't settled in. 

This is her first winter with us and she just hasn't decided to let down her guard and go to sleep. Despite her grumpiness it is calming to spend time with her. She's probably close to 90 years old. She's a wise one, she'll find a place to sleep away the winter.

Backyard Breakfast Buddies - Reptile Style!

A rescued California desert tortoise  (Gopherus agassizii) gives a little buddy a ride to breakfast.

This 2 1/2 inch long baby western fence lizard (Sceloporus occidentalis) also known as a blue-belly) is only a few weeks old, scratching out a living during Southern California's summer drought.

The the tiny western fence lizard jumped from the

white stone to the tortioses' shell.

 Maybe the lizard mistook the tortoise for another rock?

Rideshare! It's one way to save energy!

Did you know that desert tortoises have pink tongues?

 and wide nostrils to sniff out food!
