Among the thousands of species of cactus, one really stands above the rest, a species that has become what can only be described as a tree, the Saguaro. They are endemic to the Sonoran desert of Arizona, South-Eastern California, and Northern Mexico, where they form strange forests across the desert slopes. Like most other cacti, the saguaro is a stem succulent, which means they use their thick stems as the main place they store water.
The saguaro is a keystone species in the Sonoran desert with many animals using these plants for food and shelter. The blooms of the saguaro are pollinated by a range of animals, from hummingbirds to bats, with the white winged dove surprisingly being one of the most important. No animal though loves saguaro more than the Gila woodpecker, not only do they enjoy the flower nectar, but they also like to make their nests inside the cactus, drilling cavities that the cactus forms callus tissue around, creating the perfect little cavity for the woodpecker to raise a family. Each season the gila woodpecker creates a new hole, so holes from the previous seasons are available for other birds that love the saguaro, but don’t have the special drilling beak of a woodpecker, like the elf owl, the world's smallest owl.

Welcome to Ecotasia! On this channel you can find wildlife footage and short documentaries on the natural world. I am an early career biologist who was inspired by the likes of the BBC Natural History unit, PBS, and Animal Planet as a child and then more recently by various nature UA-cam channels to share my love for animals and nature. My goal is to document and highlight the interesting ecology and behavior of organisms I encounter, as well as cover and elucidate conservation and biological topics.

I guess David Grundman got himself a Darwin Award
He did indeed
Is he the guy that shot one?
@@julianugayea and it fell on him
The North American desert is somewhat alien compared to other deserts on earth, you can just feel something there, it’s a living, breathing desert. It’s so cool how literal owls and woodpeckers reside in cacti to creat a sort of natural defense against predators, and you managed to showcase that perfectly. Great video
Well the several deserts in North America are just so different, like the Sonoran has all the cacti, then the Mojave has the Joshua trees, Great basin desert is father north, it is really cool if you have the chance to ever spend some time in each of them
Natural Selection, now that's funny.
“This is what is called natural selection”
I know! Got me laughing so hard. Instant karma
Have you heard the song? Saguaro by the Austin Lounge Lizards
I had never thought about it before, but the holes of the Gila Woodpecker must be really bad for the cactus' water retention. Of course cactuses would have a great mechanism to seal off holes. They have to, or a woodpecker hole could be fatal! This was an interesting look into a new branch of biology. Looking forward to whatever information you share next!
Yeah having some fun with plants. The scar tissue is really interesting and forms a sort of jug the birds nest in.
When even cacti are dying of heat and dryness, you know you got a problem.
Another great video!
Glad you enjoyed it! Trying to make some plant content for the channel
Friend, how are you doing on this beautiful day? What an excellent video you presented to us. Beautiful cactus and many interesting facts. I enjoyed it a lot. I send you many greetings and I wish you to continue very, very well. Big hug.
Thank you so much
Saguaro catcus are often depicted in Texas related graphics despite the fact the plant does not occur in Texas.
And there is a whole fun song about it
@@Ecotasia What song?
@@lutherheggs Ain't No Saguaro in Texas
Song by The Reverend Horton Heat
Thank you for talking about CAM.
I don’t always give plants enough appreciation, but I have always loved saguaros! They are just crazy looking plants. The natural selection remark made me spit out my water, thanks for that. Great work!

They are amazing plants, part of a really amazing ecosystem. you been out to them yet?
-JJ
I love Cacti. Obviously ❤
Excellent video - I love the Sonoran ecosystem!
It really is a cool ecosystem.
Thank you🎉
You’re welcome 😊
Love your vids!
Thank you so much
This time the Giant Beat David.
I rescued an arm of a Saguaro a neighbor was cutting down in my neighborhood. Should I cover it with a wet towel to allow it a “boost” of hydration while it tries to flourish in my yard? It’s 106 today at my home and another video said they need protection’ but to NOT water the base. Your thoughts?
not sure, shade is good until they get larger
Do not water the base until 2 weeks after planting. It needs time to grow roots to absorb water. It could rot if it’s wet with no root system. Let the wound callous over. Give it a week. Then plant in the ground. You might need a shade cloth if you kept saguaro in a shaded spot while it’s wound was healing. If not, No shade cloth needed. Water it 2 weeks after planting it in the ground.
areole and areoles. Not areola. An areola is a nipple
thank you for the correction
