2. Kangaroo rat from Mojave National Preserve (near Mid Hills Campground). Desert kangaroo rat?

3. A gopher from the Black-footed ferrets near Seligman. Botta’s pocket gopher (photo taken with my mobile phone, since I forgot to take my cameras…)?

4. A rat from Madera Canyon. I saw several of these at the feeders of Santa Rita Lodge. Some kind of woodrat?

5. Another rat from Madera Canyon (maybe the same species as the previous one?). These were seen near the Proctor Road Parking Area.

6. Kangaroo rat from Borrego Palm Canyon Campground in Anza Borrego. Dulzura is the one seen there, so I guess the photo shows this species?

7. Another one from the same location.

8. A kangaroo rat from Joshua Tree, near Hidden Valley Campground. Desert?

And to end some kangaroo rats from Carrizo Plain. I mainly drove the road to Selby Campground, and saw quite some k-rats. I found these difficult to ID however… I didn’t see any foxes or antelope squirrels in Carrizo.

9. Giant kangaroo rat?

10. Another Giant?

11. Giant too?

ID for some mammals from California/Arizona – part 1

Posted July 29, 2015 by simonfeys

Hello all,
In May-June I was in California and Arizona. It was a great trip, we saw about 65 species of mammals with Black-footed ferret, Island fox, Bobcat, … (report is coming in the next weeks). However, I am still struggling with the ID of some animals, mainly chipmunks and kangaroo rats. I have pictures of most of them, and decided to split this up in 2 parts, one with the sciurids, and a second with mainly mice and rats. Thanks in advance for helping me out with these!

In Yosemite, I saw many chipmunks, which were mainly Lodgepoles, but I also saw Long-eared (Merced Grove), Shadow (Merced Grove) and Alpine (Tioga ). I found that id’ing Lodgepole and Long-eared was quite difficult…
1. Chipmunk, seen near the Toga Pass entrance. I saw an Alpine chipmunk there too, but I think the one on the photo is a Lodgepole?

2. Another chipmunk from Yosemite, this one was seen along the Tioga Road near Lembert Dome. Another Lodgepole?

3. Chipmunk, Tuolumne Grove. This one seems to have quite some white behind the ears, so Long-eared?

4. Another from the same location, also Long-eared?

5. One from Merced Grove, from where Long-eared is often reported.

6. A squirrel from Mojave National Preserve. Rock squirrel? (I saw many squirrels of this species in Arizona, but this one seems to be different).

7. Another Rock squirrel from Mojave?

8. A chipmunk from the South Rim of the Grand Canyon. Cliff was abundant here, this one looks not as grey as the Cliffs. Could this be Uinta?

9. Another one from the Grand Canyon, this one liked to climb in trees.

10. A crappy picture from a chipmunk I saw at Ten-X Campground, a few miles south of Grand Canyon. Is this a Cliff chipmunk (although the habitat was pine forest without any rocks or cliffs nearby), or Uinta (or impossible to say from this picture :-))?

11. I saw this squirrel at the same campsite, is this an Abert’s without eartufts?

12. Some bats to finish, I don’t expect these can be identified, but since I have pictures I give it a try. This one was seen near Potwisha Campground in Sequoia, they emerged well before it was dark and were pretty small – Canyon bat? Another slightly lighter and larger species was flying around at the same time here too (maybe a California myotis?)

13. Another bat, this time from Joshua Tree. This one was larger than the other bats (which I think were Canyon bats) flying around.

14. Finally, one without photo. At Tamarack Flat Campground in Yosemite I heard several bats flying around after dark, on my bat detector I could hear them best on 20 kHz.

Thanks again for any help!

RFI – Ecuador – Cuyabeno Wildlife Reserve / Southern Yasuni / Kapawi Lodge

Hi,

Has anyone been to Cuyabeno Wildlife Reserve for mammals (or birds)? And are there any lodges that stand out? Private guiding would be a must though, don’t want to be put in a group with general interest visitors.

And what about southern end of Yasuni NP (Pastaza district), are there any intresting lodges there? Even further south there is Kapawi Lodge, looks rather plush but an interesting fairly remote location?

Need ID Help – Peru – squirrel and squirrel monkeys

Posted July 24, 2015 by sjefo

Hi,

In Tapiche both the squirrels and squirrel monkeys were sometimes rather confusing:

1. Squirrels

Attached is a slightly out of focus picture of a Sciurus squirrel.

To me the hairs on the feet appear almost all red, but the hindlegs clearly show some black – does the black at the nail tips make this a Southern Amazon Red Squirrel? I think so, but not sure.

The two photos are identical, but the second has been overexposed three stops.

2. Squirrel Monkeys

The Handbook of the Mammals of the World 3 states that Ecuadorian Squirrel Monkey (macrodon) and the peruviensis form of Black-capped Squirrel Monkey both occur and intergrade in Tapiche (they specifically mention Rio Tapiche and Rio Blanco).

Some of the Squirrel Monkeys seemed to be pure peruviensis with a proper dark blackish cap, but the monkeys in these photos appear to be intergrades or even Ecuadorian Squirrel Monkeys. Can anyone comment?

Photo 1 (the “relaxing” animal) is from a different group than the other ones, which were all in the same group. One photo of three group of  3 was overexposed 2 stops in Photoshop for clarity.

Cheers,

Sjef

Vancouver Island Marmot update

Posted July 23, 2015 by John Fox

I spent the afternoon at the Mt Washington Alpine Center ski place, it was chilly, overcast and foggy; no Marmots. Hopefully tomorrow will be better.

Talking with the people at the main building, the biologists did a count last week and found more than 200 VI Marmots. They found the remains of two that they think were taken by a Cougar. One sits out on a rock from around 7am till noon in the same area V reported. They said they are most common around the Hawk chairlift which is a short walk from the main chairlift.

They also have a resident American Marten around the buildings at the main chair lift. The guy said he took a bag of trash out and opened the door to the dumpster and “hit the weasel right in the face with it”.

Cheers,

John
