Re: Ecuador Herping Suggestions

Hi Jack, In the Amazon, I highly recommend Shiripuno Lodge for birds, herps, and mammals. It is remote and relatively inexpensive, without the luxuries of the expensive Napo lodges. I walked the trails alone on my two visits, but Fernando (the lodge owner) would be an excellent guide for birds and h...

Nice! Do you have other shots of the Hemiphractus, showing the offspring a bit more...? I checked my external hard-drive, and found one showing the offspring a bit more (though most are out-of-focus): http://www.tremarctos.com/wp-content/uploads/2018/09/Hemiphractus-scutatus-2.jpg Note the unhatche...

Thanks! Do you have any advice on how to identify frogs of the genus Osteocephalus? I'm trying to identify a few before my next post.

Shiripuno Amazon Lodge, Ecuador (Part 2)

Here is my second set of photos from my trip to Shiripuno Lodge in the Ecuadorian Amazon in December 2017. My first post (on reptiles) is here: http://www.fieldherpforum.com/forum/viewtopic.php?f=2&t=24829 . This post covers terrestrial frogs and toads; I'll write another one covering treefrogs late...

Shiripuno Amazon Lodge, Ecuador

Last December, I visited Shirpuno Lodge in the Ecuadorian Amazon. Shiripuno is remote, and is known for experiencing lower hunting pressure than the Napo lodges (which matters more for mammals and birds than herps, I suppose). It has an excellent trail system, and I was allowed to walk alone, withou...

Re: Sierra Leone Herps - Identifications Needed

I cannot help with the frogs and lizards for now, but I can identify your snakes easily. The first species you identified as Grayia smithii are Blanding's Tree Snakes Toxicodryas blandingii . The second species is most likely Dipsadoboa underwoodi . If you counted scales, it may be easier to identi...

Sierra Leone Herps - Identifications Needed

I went on a trip to Sierra Leone this December, visiting two sites: Gola National Park and Tiwai Island. I was there primarily to search for mammals, and Pygmy Hippo in particular. I sadly missed my top target, though I heard one jump into the water while I was staking out a river. Nevertheless, I v...

Photos from Manu, Peru

I spent a couple weeks exploring the lowlands of Manu, Peru last summer. This was my second trip to the region, so I spent my time in areas with lower hunting pressure (read: more expensive) that would afford me a better chance of seeing some rare mammals. This didn't pan out, but I had an amazing e...

Re: Canon Prime Lens Advice (Close Focus)

Uh-oh, I don't think that's going to work. Well, it looks like you're right. I haven't worked with high-end telephoto lenses before, so I didn't consider the possibility that the "filter size" listed for the lens wasn't for the front element. This leaves me with a few options: 1. Change lenses or a...

Re: Canon Prime Lens Advice (Close Focus)

Something about buying a $7K lens and putting a diopter in front of it seems a bit off in my book.

Thanks for the diopter suggestion! I ordered a hard-to-find .62 power diopter which would give me a focus range of about 1-1.6 meters, and I'm going to rent the lens in a couple weeks to try it out. If that doesn't end up working, what macro lenses do you use? I might try to get something similar a...

Re: Canon Prime Lens Advice (Close Focus)

Excellent, hope the diopter is a success. Remember you can stack them as well to get even closer, you do lose some image quality so if you do choose to go this route get some quality ones to minimize this effect. So my designated macro right now is a 105 mm Nikkor, I use it for most of my photos. B...

Any suggestions of roads through good forest in Massachusetts that don't get any traffic at night? The closer to Boston, the better. I'm primarily looking for mammals (Fisher, Bobcat), but I suspect herpers would use similar roads.
