We begin with a spring ritual at Field Guides: Colorado in April! Here two Greater Prairie-Chickens square off at a lek in a great photo by participant Chris DeCilio.
A male Greater Sage-Grouse, head almost concealed, clearly seeks some attention with one of the most amazing avian displays. Photo by participant Steve Wakeham.
Occasionally males erupt into physical combat with shoving and wing slapping. Photo by guide Eric Hynes.
As dramatic as the behavior is at the Greater Sage-Grouse lek, the giant chickens meld into the sublime landscape. How many are in this shot by participant Bob Reed?
Did we say it could be wintry? One of the highest regularly plowed roads in the world is Route 6 over Loveland Pass. What, you ask do we seek here?
Well, the elegant White-tailed Ptarmigan, of course, and this year did not disappoint! This and previous photo by participant Chris DeCilio.
Apparently, White-tailed Ptarmigan are notorious for photobombing! Photo by guide Eric Hynes.
We have numerous non-grouse or prairie-chicken targets while out on the plains, including this subtle beauty: Mountain Plover. Photo by participant Steve Wakeham.
Our first Colorado Grouse run found some big flocks of migrant McCown's Longspurs, with many showing the tail pattern nicely. Photo by participant Steve Wakeham.
Steve captured 3 rosy-finch taxa here: background Brown-cappeds, "Hepburn's" Gray-crowned with gray head at right corner, and nominate Gray-crowned at center.
This one's a bit harder to mistake: Black Rosy-Finch. Photo by participant Steve Wakeham.
Everyone loves the charismatic American Dipper, with its unusual habits. It's spring, and this individual has a bill full of nesting material. Photo by participant Chris DeCilio.
There are some cool mammals along the way. This Porcupine looks as if it stuck its finger in a socket! Photo by participant Chris DeCilio.
There are raptors to find as well, and the North Park region of Colorado is a great area to see Rough-legged Hawks, such as this adult male photographed by guide Eric Hynes.
This American Three-toed Woodpecker was a nemesis for a number of participants; but the key word there is "was"! Photo by guide Eric Hynes.
Participant Bob Reed shared this bright image of a handsome male Mountain Bluebird, which added a serious dose of color to our proceedings.
A fine Greater Prairie-Chicken by guide Eric Hynes -- the species is always on the tour favorites list due to the visual intimacy of our experience.
We wrap up images from our two Colorado Grouse tours with this Sharp-tailed Grouse, flashing lavender air sacs during its wind-up-toy display. Photo by guide Eric Hynes.
Moving south into the Caribbean, next are images from our Puerto Rico tour. Like many participants, Larry Wright arrived ahead of the tour and explored historic Old San Juan.
Another view of beautiful Old San Juan, also by Larry: Castillo San Felipe del Morro sits at the end of the peninsula, overlooking the entrance to San Juan Bay.
Loggerhead Kingbird is a Caribbean specialty, and Puerto Rico hosts a recognized subspecies. Photo by participant Larry Wright.
Puerto Rico has an endemic Myiarchus flycatcher and, as with many of the endemics, the island is in the name: Puerto Rican Flycatcher. Photo by participant Larry Wright.
Venezuelan Troupial is a species introduced to Puerto Rico, but it is too beautiful to ignore. Photo by participant Larry Wright.
Yellow-shouldered Blackbirds are only found in the southwestern part of Puerto Rico and are critically endangered. Photo by participant Larry Wright.
The endemic Adelaide's Warbler is fairly easy to come by in Puerto Rico's dry, scrubby forests and edges. Photo by participant Larry Wright.
Island-hopping to another set of images, this classic Caribbean scene on Eleuthera Island is by guide Jesse Fagan from his recent Bahamas Endemics & Kirtland's Warbler tour.
Gotta see Kirtland's Warbler since it's in the tour title -- and we have every year! This handsome bird by guide Jesse Fagan is one of three we saw well this trip.
