Some Type Of Whiptail
« on: February 29, 2016, 07:54:35 AM »
Originally I was told by a volunteer this was a Checkered Whiptail, but I'm not sure.  In fairness to the volunteer, they were viewing the pic on the camera at the time and not printed or posted online.   I was thinking Tiger Whiptail.  Any thoughts?

Having decent gear is nice, but wildlife photography is knowing your subject and getting lucky, and I love getting lucky.

I'm with you on this one.  Checkered Whiptails tend to be, as the name implies, quite checkered along their dorsums, and this one has a more reticulated pattern.  It also has a prominent post-orbital spot, which is much less prominent in the Checkered Whiptail. There's no scale on this image, but Checkered Whiptails are the largest of all whiptails, at least a foot in length, and this one doesn't appear to be that long.   I think it's Aspidoscelis tigris, known as the Western or Tiger Whiptail.  The real clincher would be to check the scales on the back of the forelimbs;  in Tiger Whiptails they are enlarged compared to the other scales on the legs, but I don't think you can tell this from the image.

Thanks Johnathan,

Would you know what this critter is?  Ranger said it was a Crevice Spiny Lizard, nut I'm not finding much to verify that.  Guess I need to buy Lizards of the American Southwest and see if it helps.

I'll nominate Johnathan to be the BBC resident herpetologist.  Awesome ID of ambersdad's lizard pic!

Yes, it looks good for Crevice Spiny Lizard (Sceloporus poinsettii).  The black collar (which he's puffing up - excellent shot!) is distinctive for this species, and the blue throat and abdomen show that he's a male, likely doing a territorial display.

Thanks, although I think your estimation of me is a bit grandiose.  My background is in geology, although I've also taught courses in environmental science.  One thing you learn in geology is how to identify rocks and minerals, and you can use the same skills to identify wildlife (except the wildlife tends to move around...).  All it takes is careful, detailed observation and the proper reference material.  When I go travelling around, along with the necessary hiking and camping gear I carry a box full of reference books, including field guides for birds, mammals, reptiles, and trees, and I use them to try to identify what I've seen and photographed each day.

That's not a horny toad, is it? Hard to tell not seeing a front shot. Good photo.

Well, certainly not a toad, at least.  :eusa_dance:
