What type of lense do you recommend for the fly outs and fly ins. Also, how do you keep the lenses from fogging in the cold temperatures. This will be my first visit.
If anyone from that area would like to have a phone conversation about the experience send me message wiht you phone number or let me know and I will send mine.

I don't know anything about Bosque, but as far as lenses fogging, it's changes in temperature and humidity that do it. If you let the lenses adjust to the outside temperature, you shouldn't have any problem with fog (don't breath on them or anything of course). Some people even store their camera equipment outside overnight if it's going to be cold, so there's no adjustment time in the morning.
Of course, then you have to be careful about getting condensation in the lens when you bring it back inside as well - keeping it (and your camera) sealed up in a bag while the temperature adjusts is a good idea...

Carroll, try this photo site www.pbase.com/henryhwong/sandhill_crane Photos' information includes some metadata which should help you.
We arrive there on Friday,11/14 for weekend of shooting. I will be using a 100- 400 with a 1.4x on my 20D for pre-ascension and landing. Bringing a 70-200 in case I can get closer to birds while they are feeding in grain fields.

Bringing a lens from a warm environment to a cold one won't cause any condensation issue. Going from a cold environment to a warm one will fog everything (or frost, if the lens is cold enough).
I had an interesting experience recently with keeping my gear in the car overnight. It got moderately cold, in the 25 F range overnight. I then shot in the early morning, in rapidly warming temperatures (eventually to the low 60's) in a moderately moist environment. As near as I can figure, the lenses didn't warm up as fast as the air, so I wound up with condensation on the front element. It took hiding the camera and/or lens (depending on the format) under my sweater to heat everything up, to allow me to shoot. Given that experience, I'd probably keep the camera in the motel room until you are ready to leave.

I just had a similar occurrence as Dan. Camera and lenses in a bag in the Jeep overnight, fogged up when I removed the lens caps in the morning. Once I saw it happen the first time, I removed the caps from all my lenses and just let ambient air temps work their magic for a few minutes till they were clear. I guess my first lens didn't fog up because it was still relatively cold at the time I took off the lens cap....

Normally you will not have serious fogging problems at the Bosque. I keep my gear in the room overnight, and have never had a problem in over a hundred visits. For flyin and flyout I use a 400 .28 with teleconverters, but the most common long lens I see is a 500mm, with the occasional 600 or 800mm.
