The three black stigmas (sections of scent glands that produce pheromones) on each forewing distinguish them from other grass skippers, a large subfamily whose larvae often feed on native grasses. Note the hooks at the end of their antennae clubs and the doe-like eyes, two characteristics of most skippers. https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/212ef60e-a9d5-43a2-8c00-8588b37763a4/TaxilesSkipper_StephenJones.jpg Articles - August Nature Almanac: Skippers Flit through Mountain Meadows - Make it stand out Taxiles Skippers have bright orange wings with dark margins, which distinguish them from the closely related woodland skippers. Females can wait patiently in the sunlight for hours while assessing the fitness of a potential mate. https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/3b0f2466-fe9f-4867-bacf-11f513368c9a/DunSkipper_StephenJones.jpg Articles - August Nature Almanac: Skippers Flit through Mountain Meadows - Make it stand out We found this dun skipper perching on a ponderosa pine needle, though they tend to lay their eggs on native sedges. Their name derives from their dull brownish color, but recently emerged individuals may have distinct white wing margins and gold tinting of their heads and wings. https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/8998c70c-c36f-40b4-9c67-8bab355e0ae9/ArogosSkipper_StephenJones.jpg Articles - August Nature Almanac: Skippers Flit through Mountain Meadows - Make it stand out Arogos skippers deposit their eggs on big bluestem and other tallgrasses, and they gather by the dozens on sunflowers and thistles during July and early August. Though fairly common in the lower foothills of Boulder County, they are thought to be threatened throughout the western plains by loss of native grasslands. Note the unmarked orange wings and white wing margins. https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/9da6bb3e-b20f-4840-afb7-4b1a6e237901/WesternBandedSkipper_StephenJones.jpg Articles - August Nature Almanac: Skippers Flit through Mountain Meadows - Make it stand out Western branded skippers are among several locally occurring grass skippers with intricate arrangements of white spots and chevrons on their wings. A clear photo and a good field guide (such as Jim Brock and Ken Kaufman's Butterflies of North America) are often necessary to distinguish among these similar-appearing wonders. https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/eae9bed9-4523-4af2-a53f-3176ae8df677/CommonCheckeredSkipper_StephenJones.png Articles - August Nature Almanac: Skippers Flit through Mountain Meadows - Make it stand out Common checkered-skippers are among the spreadwing skippers, species that when perched lack the "jet airplane-appearance" of other skippers. Inhabiting a variety of habitats from coast-to-coast, they are considered the most abundant and widespread skipper in North America. https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/f22ad7fc-6fa9-4504-8e77-c918f417bfff/SilverSpottedSkipper_StephenJones_s.jpg Articles - August Nature Almanac: Skippers Flit through Mountain Meadows - Make it stand out Silver-spotted skippers stop us in our tracks with their relatively large size, graceful appearance, and striking silver patches. They lay their eggs on locusts, wisteria, and other legumes. This individual is sipping on snowberry blossoms, which attract legions of butterflies to our lower foothills canyons. https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/3e6b4f6f-6b62-4a3d-b4b5-aff9474c0368/Gentian+Arctic_StephenJones.JPEG Articles - August Nature Almanac: Skippers Flit through Mountain Meadows - Make it stand out Arctic Gentian. https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/3a319765-6a53-46b0-a806-2eb1ea16a818/Chipmunk+siblings+on+stump_StephenJones.jpg Articles - August Nature Almanac: Skippers Flit through Mountain Meadows - Make it stand out Juvenile Colorado chipmunks. https://www.boulderaudubon.org/articles/july-2024-na monthly 0.5 2024-07-07 https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/a3fb1660-4276-4924-b81a-a13c1a95dd6d/Ovenbird_MikesBirds_CCBY-SA.jpg Articles - July Nature Almanac: Ovenbirds Fill Foothills Canyons with Exotic Song - Make it stand out Ovenbirds may not look like other wood-warblers and shouldn’t be confused with South American ovenbirds.

They also were not any of the orange butterflies I was seeing. The first time I saw a wild monarch butterfly was the day I took this photo. I was very excited to finally see this butterfly that I had heard so much about! I was especially delighted that I got the photo while it was sitting on a milkweed flower, the monarch’s traditional food source.” https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/1618264088182-NCAJQSG4DHQLMPWJV9ZB/Larkspur_EvaGetman.png Articles - Teen Naturalists Uncover Tallgrass Treasures Prairie larkspur.

Nests in brushy woodlands and forest edges from New Mexico and Colorado (west slope only) and California north to Alaska and Newfoundland. - Conservation: Breeding Bird Survey data indicated a 1.9% decline throughout the United States from 1966-2012. Encroachment of human habitations into shrubby areas and forest edges may have reduced nesting habitat.

Nests on the ground under shrubs throughout the southern Rocky Mountains and Great Basin region. - Conservation: Doing very well in Boulder County, where increased shrub growth in the foothills after the removal of grazing cattle has enriched nesting habitat. In contrast, fire suppression in mountain conifer forests has reduced nesting habitat by suppressing shrub growth.

Easily identified by its breathy, descending "sweet-sweet-sweet, I'm so very sweet" song, often delivered from high in a cottonwood. Nests throughout North America from Alaska south to central Mexico. - Conservation: Boulder County nesting populations have thrived as deciduous woodlands proliferate along prairie streams and in urban settlements. Breeding Bird Survey data indicate that populations throughout North America remain stable.

Their Boulder County nesting range overlaps in the foothills and lower mountains with that of Virginia's warbler, whose song they may "adopt," sometimes rendering identification by ear challenging. - Conservation: Abundant in conifer forests from 7500-11,000 ' and probably our most common Boulder County warbler. Nesting populations appear stable throughout most of the mountains of western North America. Still one of our most common migrants on the plains and in the foothills in May and September.

Nests in conifer forests of northwestern North America, from Wyoming to Alaska. - Conservation: Breeding Bird Survey results indicate that North American nesting populations are stable. Number observed in Colorado during migration probably depends in part on availability of insects in mountain conifer forests.

Their call is a sharp, harsh tsik, similar but slightly lighter than that of dark-eyed juncos. They nest throughout the mountains of western North America wherever dense undergrowth is available. - Conservation: Ski area construction and other disturbances of mountain willow carrs and montane shrublands have reduced available nesting habitat in Colorado. Breeding Bird Survey data indicate a statistically significant 0.8%/year decline in populations throughout the United States from 1966-2012. Photo © 2013, Glenn Bartley https://images.squarespace-cdn.com/content/v1/605774b62adaca3d245caad5/a8120166-900c-43d2-8958-83a0ecab4364/WilsonWarbler.jpg Regional Birds - Wilson's Warbler - Status: Fairly common summer resident in wet mountain forests and willow carrs. - Populations: These active, yellow-faced warblers nest in dense bogs and willow thickets, primarily above 8500'. Their song is a series of chee notes, generally on the same pitch and slower than the song of yellow warblers. They nest in boreal wetlands of North America from Colorado and California north to Alaska and Northwest Territories, and across central and northern Canada to Newfoundland. - Conservation: Breeding Bird Survey data indicate a 1.8%/year decline throughout North America from 1966-2012. Destruction and fragmentation of mountain willow carrs by various human activities can reduce nesting populations.

Each spring and early summer, a few males are heard singing in foothills deciduous woodlands of Boulder County, but nesting has never been documented here. Most easily found by the male's distinctive song, a series of high, thin notes usually followed by a down-slurred note. - Conservation: Since they thrive in open deciduous habitats, American redstarts have benefited from clearing of some forest areas. However, loss of deciduous woodlands throughout much of eastern North America has impacted nesting populations, and Breeding Bird Survey data show a statistically significant decline of 1.5%/year throughout the United States from 1966-2012.

Males perch prominently in foothill shrubs, emitting an unrelenting stream of whistles, grunts, squawks, chattering clucks, and rattles. Males often sing right through the night. - Conservation: Nesting populations have probably increased at the base of the Boulder County foothills as grazing cattle were removed from shrubby areas. Breeding Bird Survey data indicate a 0.6%/year decline throughout North America from 1966-2012.

Nests on the ground in dense vegetation. - Conservation: Proliferation of cattail marshes around gravel mining areas has probably benefited these marsh-nesting warblers in Boulder County, though most of the original wetlands where they nested historically have been destroyed. Breeding Bird Survey data indicate a 1.0%/year decline throughout North America from 1966-2012.

Though not uncommon in Gambel oak woodlands of the southern Front Range, nesting pairs appear rare in Northern Colorado, where absence of oak leaf litter makes nest building a challenge. Here in Boulder County we observe several singing males each spring and early summer but have never documented nesting. - Conservation: North American populations appear to be stable. Numbers appear to have increased in western Nebraska and along the Colorado Front Range as deciduous tree and shrub growth has proliferated in canyon areas.
