Back to Corkscrew Swamp Sanctuary

CorkscrewSwamp-FL_LAH_5943

Home to birds, mammals, reptiles, and very nice people—Audubon’s Corkscrew Swamp Sanctuary has it all. Last winter I made my second visit there, five years after the first. It may have been snowing at home in Colorado, but southern Florida was supposed to be warm—wasn’t it? The day before had been lovely, but this morning dawned damp and gray, with tendrils of fog creeping over the wetlands. I arrived at 7, just as the admissions office opened, knowing I had to be done to meet Pete for lunch. Well, a late lunch, at least! I wanted to make the most of my time as I walked the 2.25 mile boardwalk.

The AOU’s 2019 Bird List

Hawk Trip-ElPasoCo-CO_LAH_6738Every year, the American Ornithological Society (AOU) reviews a number of proposed changes to the classification of North American birds. This affects the definitive list on which we birders base our life lists. Species may be added or deleted. Sometimes, a species is divided into two or more new species, such as the split of the Western Scrub-Jay a few years ago. (I gained a new life species as a result, as I have seen and photographed both the California Scrub-Jay and Woodhouse’s Scrub-Jay.)

Other times, species may be lumped together—what was once considered two species is now thought to be only one, with various subspecies. Sometimes, entire genera are moved into new families. Or, a species remains unchanged, but the name is updated, as when the Gray Jay became officially known as a Canada Jay.

Brown-headed Cowbirds

Brown-headed Cowbirds have a bad reputation. A lot of birders don’t like them because they seem to be shirking their parental duties. Because they are obligate brood parasites—they don’t build their own nests, and only lay their eggs in the nests of other species—we accuse them of taking advantage of other species by forcing them into doing all the work of feeding a hungry nestling. It’s unfair. We’re indignant.

A Visit to Castlewood Canyon S.P.

CastlewoodCanyonSP-CO_LAH_3614_filtered

Not to stay home on a gorgeous Saturday morning, I joined our Audubon chapter field trip to Castlewood Canyon State Park, located on the Palmer Divide between Colorado Springs and Denver. At elevations between 6,200 and 6,600 feet, the park includes ponderosa forest, dry shrubland, high prairie, and riparian areas. This diversity allows for plenty of birds, a colorful array of wildflowers, plus some pretty impressive scenery. Our loop trail along the canyon rim, down to (and across) Cherry Creek and through the riparian willows, then back up to the parking lot clocked in at 3.2 miles, but you could easily add some side trips.
