To: Colorado Birds <cobirds@googlegroups.com>, David Suddjian <dsuddjian@gmail.com>Scott Rashid presents "Blue-Mmers are back! Bluebirds and Hummingbirds: Get ready for two of the most beloved birds in North America." On Zoom with DFO at 7pm on March 30.
Register here for Blue-Mmers are Back
Come join us for DFO's free Zoom webinar with Scott Rashid presenting on two of the most beloved groups of North America birds, bluebirds and hummingbirds. Bluebirds arrive in Colorado in February, and the hummingbirds appear in April. The focus will be on Scott's home area of the Estes Valley and Rocky Mountain National Park. For the bluebirds, learn about the habitats each species prefers and where they can be found, where they nest, and where to place nest boxes for them. Enjoy images of their eggs, nestlings, and fledglings. Scott will also discuss the hummingbird research he has been conducting for more than a decade. Scott will share the amazing adaptations that only hummingbirds have, including their unique ability to fly in any direction (including backwards!) and what their colored throat patch is used for. See images and videos of courtship activities, feeding, nest building, and the females feeding their young. Learn the proper mixture of sugar and water to fill your feeders, and how to properly care for them.

[cobirds] Dinosaur Ridge - Denver Field Ornithologists (28 Mar 2026) 43 Raptors
Dinosaur Ridge - Denver Field Ornithologists
Golden, Colorado, USA
Visitors:
8 Visitors. We had a nice group visit in the morning! One young visitor enjoyed spotting as many birds as he could - when his dad asked if hawkwatching or TV was better, he said hawkwatching without hesitation. Thank you to our wonderful volunteers Sara Painter and Lauren Friesen today! We appreciated your spotting, especially in the heat of the morning.
Weather:
This morning started sunny with scattered clouds and thin wispy cloud cover, with temperatures climbing to the high 70s to low 80s by mid-morning. In the afternoon, the skies gradually became overcast and temperatures cooled slightly. A few raindrops fell at one point, but not any real precipitation. Winds were light to the E and SE throughout the day.
Raptor Observations:
We had another day of good movement with Red-tailed Hawks moving in the morning along with some Cooper's Hawks, American Kestrels, and a few Turkey Vultures. A local pair of Cooper's Hawks were also seen together, with the male performing an aerial display with slow deep wingbeats. The birds became less active overall once the cloud cover intensified from thin to overcast, although this didn't seem to deter the falcons, and we had a distant Merlin on the west side. The highlight of our day was our first Peregrine Falcons spotted at the ridge! The first came by mid-day on a direct path north. An hour or so later, we saw two at once circling high overhead- we suspect this may be our local pair that's breeding at Red Rocks. Finally, we saw another PG at eye level right barreling past the ridge - it was out of sight in a matter of seconds.
Non-raptor Observations:
Common Raven 12, Tree Swallow 3, Mountain Bluebird 1, House Finch 1, Pine Siskin 2, Spotted Towhee 1, Western Meadowlark 1
Predictions:
Tomorrow, we expect high temperatures and lots of sun, with a few afternoon clouds. Winds are predicted to be light from the W and NW, with possible moderate gusts. For those with allergies, tree pollen is predicted to be high to very high for the next few days. Trails are dry.

Site Description
Dinosaur Ridge is the only regularly staffed hawk watch in Colorado and is the
best place in the world to see migrating Ferruginous Hawks. Hawk watchers may
see 17 species of migrating raptors; and it is an excellent site to see rare
dark morph buteos including Broad-winged hawk, Swainson's hawk, Ferruginous
hawk, Rough-legged hawk and Red-tailed Hawk. Other raptors we see include Golden
and Bald Eagles, Northern harrier, Osprey, Peregrine Falcons, Prairie Falcons,
Cooper's and Sharp-shinned Hawks, American Kestrels, Merlin, and Turkey
Vultures. American Goshawk is uncommon but also counted each season. Non-raptor
species include Rock Wren, Bushtit, Western Bluebird, Sandhill Crane,
White-throated Swift, and American White Pelican. Birders of any skill level are
always welcome. The hawk watch at Dinosaur Ridge is staffed by Hawk Counter(s)
and volunteers from March through early May.
Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take left
into first parking lot, the Stegosaurus lot. Follow hawk watch signs from the
southwest end of the parking lot to the hawk watch site. The hike starts heading
east on an old two-track and quickly turns south onto a trail on the west side
of the ridge. When the trail nears the top of the ridge, turn left, and walk to
the flat area at the crest of the ridge. (Distance: 0.56 miles, Elevation gain:
259 feet)

[cobirds] Dinosaur Ridge - Denver Field Ornithologists (27 Mar 2026) 66 Raptors
Dinosaur Ridge - Denver Field Ornithologists
Golden, Colorado, USA
Visitors:
5 visitors. We had a few birders visit the ridge today in the last hour. They had wonderful views of a female Northern Harrier low overhead before it circled higher into the sky. Thank you to Holly Houser, Helen Berkman, Leslie Dixon, Mike Fernandez, and Myron Gerhard for volunteering today!
Weather:
The morning started overcast and cool, a drastic change from prior days. Visibility was slightly decreased by fog. We had overcast skies until mid-afternoon, after which the cloud cover started to clear. By the end of the day, thin and partial cloud cover remained and skies were sunny. Winds were light from the E throughout the day, shifting to NE in the final hour of the count.
Raptor Observations:
In the cool and cloudy morning, we had an early push of migrants, and many eagles were active including 2 migrant BEs and a GE. After this initial period, activity was very quiet until midafternoon when the clouds shifted. When the sun came out, so did the raptors! Thermals were quick to develop - First on the smaller peak north of Mt. Morrison. Many birds took advantage of this, and at once point 3 Cooper's Hawks were seen at once along with a few RTs. Later, a thermal developed directly overhead and more RTs came in. At once point we had twelve circling overhead and we counted them as they streamed out, even as more birds joined them. After this excitement, things slowed down but we had a few accipitrines and RTs continue on the west. An interesting dark morph Buteo was seen to the east with a cleanly banded black-and-white tail - possibly an early BW but looks were brief. We will have to see what the future holds. We also welcomed back our local Rock Wren today!
Non-raptor Observations:
Canada Goose 8, Great Blue Heron 3, Northern Flicker 2, Magpie 4, Black-billed Magpie 2, American Crow 1, Common Raven 3, American Bushtit 6, Rock Wren 1, Western Bluebird 1, American Robin 1, Pine Siskin 2, Spotted Towhee 1, Western Meadowlark 1, Red-winged Blackbird 1, Common Grackle 2
Predictions:
Tomorrow, temperatures are forecasted to rise throughout the day, starting in the low 60s F but approaching the high 70s in the afternoon. Cloud cover is predicted to vary from few clouds in the morning to partly cloudy in the afternoon. Expect light to moderate winds to the west and southwest.

[cobirds] Dinosaur Ridge - Denver Field Ornithologists (26 Mar 2026) 158 Raptors
Dinosaur Ridge - Denver Field Ornithologists
Golden, Colorado, USA
Visitors:
We had 11 visitors stop by during our busy day today. Thank you to our fabulous volunteers Cayce and Chris Gulbransen, Dale Campau, Ryan Gannon, and Jeff Birek for their help spotting distant birds today. Busy days like today would be much more chaotic without your help.
Weather:
As we arrived to the ridge today winds were gusting higher than expected. Temperatures were high and clouds were scattered. Winds quickly died out revealing even warmer temperatures that settled in for the day. Cloud cover increased throughout the day before covering the sky when we left. Winds shifted a few times throughout the day but mostly stayed calm until the end of the day. A cold front is moving through this evening and we saw that in lowered temps and light precipitation on the hike out. Smoke from wildfires in Nebraska moved into the area in the late afternoon impacting visibility greatly.
Raptor Observations:
What a day! Today was our highest count in March since 2022. The flight started immediately when we arrived and continued through about 1730 MST. Birds took the common western line- first spotted around Mt Morrison before getting great heights and heading N. Red-tailed Hawks dominated much of the morning for species, with American Kestrels dominating the second half of the day. In the early afternoon we had our busiest hour of 51 birds! During this hour birds seemed to pour out of the sky overhead and west of us, with the occasional bird coming E of us. Highlights of the day include our FOY Osprey (three of them!), our FOY American Goshawk (a distant juvenile), and a number of close overhead Northern Harriers. We also got to enjoy our first kettle of Turkey Vultures.
Non-raptor Observations:
Feral Pigeon 2, Sandhill Crane 4, American White Pelican 10, Steller's Jay 1, Woodhouse's Scrub Jay 1, Common Raven 2, Black-capped Chickadee 2, American Bushtit 3, American Robin 2, Western Meadowlark 1
Predictions:
Precipitation may come in overnight leaving temperatures low tomorrow with heavy cloud cover. The trail may be muddy.
