Holbrook Reservoir

My birding year got off to a great start back in January, helped by my trip to Florida. By the end of January, I’d already seen 133 species. I had trips to Arkansas in April and Ohio in May and figured this would be a banner year. Then the virus hit and the trips were cancelled and I couldn’t even go very far in Colorado. I went along with the restrictions until it became evident that the restrictions were excessive and probably weren’t helping anyway. But as the peak of spring migration approached, I decided to break out a bit. I’ve still been avoiding people and haven’t been stopping at stores or restaurants, but I’ve been driving further. Still, I identify as being at home, so that should be good enough.

On Sunday, I drove two hours down to Rocky Ford to bird at Holbrook Reservoir. I had the place to myself for the three hours I was there and enjoyed myself tremendously. There were birds galore. I saw 50 species, including 13 new ones for the year. With the Cliff Swallows I spotted on my way home, I now have 200 species. It can still be a good year, but not like it was shaping up to be.

This Semipalmated Sandpiper hung around for a few minutes at the base of the boat ramp.

I later saw a flock of them on the far side of the reservoir. I tried to get good photos. When I got home, I checked out the photos and found a Western Sandpiper in the mix. It’s the rufous bird in the lower right. The rest of the birds in the photo are Semipalmated.

A Willet. Not long after I took this photo, it flew off, giving me great looks at the white flashes on its black wings. It’s a big shorebird, with a body about the size of a Rock Dove.

Near the Willet was this Baird’s Sandpiper. They’re usually up on the dryer parts of the shore, but this one was wading in shallow water by the foam. The key marks are the buffy wash, the black spots on its back, and the wing feathers that are longer than the tail.

I saw Black-necked Stilts in the distance and I was hoping I could get close enough for a reasonably-good photo. Then two of them walked by 30 feet away as I was sitting in my car. They’re one of the birds that are pretty much all field mark. This is by far the best look I’ve ever had at stilts.

An American Avocet wandered by and had a brief tiff with one of the stilts. My photo didn’t come out great but you get the idea. I like the way the stilt just leaned away.

The avocet continued in the area for a while.

There were a lot more in the neighborhood, including this clump.

Two Marbled Godwits were wading in deeper water. This was my 296th species for my Colorado state list. These things are huge, with a body the size of a Mallard’s.

Seven Long-billed (I think) Dowitchers were hidden in the weeds. I include the photo because it’s the best I’ve gotten of them in breeding plumage.

I parked on the far side of the reservoir and walked down near the shore. Even though the light was behind me, from that spot the birds were further off. There were maybe four American White Pelicans on the lake. This was the closest I got to one. The birds on the left are Western Grebes. American Coots are in the foreground.

Many more Western Grebes were out further in open water. I also spotted a pair of Clark’s Grebes doing a courtship dance, but they were so far out I couldn’t get a photo. This is the best I could do. You can see the paler sides and the hood that doesn’t extend down to surround the eye. The bill is also brighter yellow.

This Rock Wren flew up out of roadside brush and landed on a wire. There were no rocks around, but I have found them in somewhat similar habitats before. They don’t always hang out in canyons.

I got very close to this Bald Eagle that was perched in a dead tree along the road, but it was perfectly backlit, so I had to play with filters to get any details.

Days like this are why I bird. By myself, tons of birds, many of which I don’t see often. Time to take my time and enjoy and discover. It was four hours of driving for three hours of birding, but it was definitely worth it.

Back to Clear Spring Ranch

I couldn’t stand the thought of wandering locally to bird yet again, so I drove down to the south end of the county to Clear Spring Ranch. Nothing exciting had been reported from there, so other birders didn’t flock to the place like they did last weekend. In fact, except for a couple on horseback late in the day, I had the place entirely to myself for the four hours I was there. The birding, with one exception, was pretty mediocre — winds were gentle but from the north.

The exception was this Broad-winged Hawk, my first for Colorado and my 295th Colorado bird. It was harassed from this perch by an American Kestrel. I followed it as it flew to two other perches. The kestrel stayed on the job, and finally the Broad-wing gave up and circled up and out of sight.

But the highlight of the day came early. I had only been there for maybe 20 minutes. I was at the south end of the trail and noticed an odd-looking “squirrel nest” in a large cottonwood. A glance through my binoculars revealed a sleeping porcupine. I lightened this photo considerably because at the angle I took this photo, it was silhouetted against the morning sun.

I never did see it move, but by the time I’d worked my way around through the woods, it was in this position, so I know it was alive.

It was about 30 feet up in the tree and it paid me no attention whatsoever as I maneuvered for the best photo. In total on the day, I walked 8.2 miles and saw 34 species of birds.

Clear Spring Ranch

On Saturday, somebody reported a Glossy Ibis and several Long-billed Curlews hanging out in a flooded field at Clear Spring Ranch, near the southern edge of El Paso County.

It’s week five of the Covid-19 quarantine, and as the major push of spring migration gets closer, I’m getting antsier about being locked up. Apparently a lot of other local birders feel the same way because it sure seemed like most of them headed to Clear Spring Ranch on Sunday morning. It’s about as far as I feel confident going during this bizarre suppression of my freedoms.

I arrived around 7:30, but there were at least three birders there ahead of me. There were four White-faced Ibises in the field, along with Franklin’s Gulls, both yellowlegs, five species of blackbirds (Red-winged, Brewer’s, Yellow-headed, Common and Great-tailed Grackles) and a smattering of other stuff.

White-faced Ibis. I lightened a few of these, but I assure you I didn’t add any color.

Franklin’s Gulls. Again, no color has been added. Their undersides really are tinged with pink in breeding plumage.

Here’s an answer to the age-old question: How much greater is a Greater Yellowlegs? You can see the size difference when they’re together like this. Also notice the longer bill on the greater, with something of a curve upwards. The greater also has more barring on its side.

I walked the trails for an hour or so but didn’t see much. I did hear a calling Virginia Rail. A ranch that borders the trail now has a bison in the pasture with the horses. I took a photo and messed around with it a bit.

I also took a photo of the railroad bridge over Monument Creek and applied some filters.

After leaving Clear Spring Ranch, I drove out into the flats in search of other birds. If I knew then what I know now, I would have stayed at Clear Spring and walked around some more to get in exercise and spare myself 50 miles of mostly-pointless driving.

I did finally get some halfway decent shots of Burrowing Owls, but my camera still has trouble focusing on brown against brown.

And that was just about it. I probably would have stayed out longer and found another place to walk, but some afternoon thunderstorms blew through, stirring up the wind and making birding unpleasant.

Social Distance Birding

I got tired of passive social distancing, so I opted for some active social distancing. I left home at 6:30 and stopped by Memorial Park to look for the Neotropic Cormorant that’s been seen there earlier this week. I didn’t see it, but I did find this Double-crested Cormorant with a fishing line dangling from its bill.

I drove down to Squirrel Creek Road and stopped by the prairie dog town that is generally reliable for Burrowing Owls. There were six owls there (along with two Pronghorn, two Swift Fox, and a ton of Black-tailed Prairie Dogs). I must have taken 50 photos of Burrowing Owls during the morning, but none of them came out well. This is the best of the bunch. My camera struggles with brown animals on a brown background.

In this part of the state, it’s hard to find people, much less get within six feet of them.

I stopped for some grocery shopping on the way home and wore my “mandatory” mask for the first time. Supposedly a mask is required when shopping, but at least a third of the shoppers didn’t have one.

Mammal #71 — Swift Fox

El Paso County, Colorado — Squirrel Creek Road

I got tired of being cooped up in my immediate neighborhood by the virus, so I got up early and headed out into the desert flats in the eastern half of El Paso County. I drove out Squirrel Creek Road and stopped by the prairie dog town that has been reliable for Burrowing Owls. I saw six owls there today, but my attention was immediately drawn to a pair of Swift Foxes that were hanging about the mouth of their burrow maybe 60 yards from the road.

During the 20 minutes I watched, they never moved more than a few feet from their burrow. They were actively relaxing — lying down, sitting up, walking around, going in and out of the burrow. They looked my way from time to time, but didn’t seem to be bothered by my presence.

Swift Foxes are tiny, about 12 inches tall and 30 inches long from the tip of the nose to the top of the tail. That’s about the size of a large house cat. I thought they actually looked cat-like at times. They’re nocturnal, but obviously you can also see them if you get out early in the morning. They’re called Swift Foxes because they can run up to 30 mph. They nest in abandoned badger or prairie dog holes. Swift Foxes eat small animals, birds, insects, and fruit and nuts. The identifying marks, apart from size and habitat, are the black tail tip and black patches on the sides of the muzzle.
