Our forays into bird watching are casual. An unusual sound is heard, curiosity. A bright colored boy catches the eye. (Saw a big bright Mexican parrot in a canyon in the Chiracahuas.
There are corridors of riparian water and the ranges of "sky islands" that bring, I'm thinking 2 to 3 hundred bird species through Arizona, concentrating most of them. I remember my niece had to know around 230 to get her forestry degree. There have been places where I've sat and listened and heard six to a dozen bird calls within much less than a minute. Birders come from all over the world.
We're always looking to travel light and photograph, so the extra binocular is rarely taken with. DF's telephoto is powerful like binocs, so we on occasion take a zoom on an object, set it to the big computer screen at home and then blow it up from there. The birds are tough to nab, with light, shadow, depth of field, focus on the bird in a tree and get a sharp image of the branch in front of it.
I bought a state of the art pair back in the 1980's which are very compact, cool looking camouflage and cushioned. Boynton 8x21 that sit in my console in my truck, but rarely are used. We just take a photo. They have come in handy while speeding in the country to have a spotter.
Satisfied with that equipment for years, a couple of pairs of old tech military, (think WWII) were inherited. Then, on this last big trip in the Valley of the Gods, I came across a pair of Nikon Monarch 8x42 lying lost in a remote wash! Someone hadn't noticed the loss while climbing up a shelf and they fell quietly to the sand below. Dang! Technology has improved! These are very fun, stars, the moon eclipse, we even nabbed a curious bird sighting, or two. Still, they are extra bulk and weight to lug on a long hike, when we are looking to document and feel nude and light.
Yea, pocket moths...I'd have to find a high-end metal detector used, from someone who hardly used it, get it cheap, so I could resell it without much loss, when I'm the guy with a hardly used high-end metal detector. But then again, I might strike a pebble and get pulled into GOLD FEVER!
