Anna's Hummingbird in the Back Yard


The birds of summer have been active in our backyard, letting us know in no uncertain terms when the food offerings are running low. The hummingbirds have been especially active, buzzing close to our heads if the sugar water is not up to their high standards. But if the water is fresh and full, they'll hang around for a picture or two. Today's visitor is an Anna's Hummingbird (Calypte anna). 

According to the Sibley guide, there are sixteen species of hummingbirds to be found in the American West, but in our county only six species have ever been noted. Of them only the Anna's Hummingbird is a year-round resident. Black-chinned Hummingbirds are relatively common during the summer, and Rufous Hummingbirds migrate through the region in the fall and spring. The other three are rarely seen. 

Overall the lack of diversity simplifies hummingbird identification at our feeder. The orange-colored Rufous can't be mistaken, and the Black-chinned will have purple iridescence around the neck. The Anna's are magenta, although it's off a bit in these pictures because of the reflection of the feeder.

I do wish they would get along at our feeder. They are territorial about their food supply and will spend more time chasing intruders than they do eating!

Killdeer Babies on the Tuolumne River!

The pictures are not as clear as I would like, but you can see them! The Killdeer chicks were born this week!
It's always a bit scary for the Killdeer mama (Charadrius vociferus). They love setting their nests on rocky open ground, and the only such ground locally is around the concrete margins of the Waterford sewage treatment facility. The gravelly surface is traversed constantly by maintenance trucks. I do know however that the employees are careful when they know a nest is present, as they will put a pylon out nearby to warn drivers. But there was no evidence that they had detected this nest, so I just worried for weeks as mama tended to the eggs.

Having nests out in the open like the Killdeer prefers is also perilous because of the threat of all manner of predators. There are cats, foxes, otters, and rats in the area, as well as kestrels and ravens. The Killdeer eggs are well camouflaged among the stones, and the bird is famous for its broken-wing strategy of distracting predators away from the nest.

Still, I was distressed to see that the nest seemed to be abandoned in the last few days, and I worried, but today I saw the almost comically small killdeer chicks running around after their mother.

What to do when you are stuck indoors? Why, look out the window!

I've been sidelined by the worst cold ever, and haven't been able to see my beloved river trail for several days. Spring has arrived and I have been looking hard for the spring migrants that have been arriving in the region, and really felt like I was missing out.
But wouldn't you know that backyards with feeders can actually attract some of those migrants? We've had them before in previous years, but it still takes your breath away when you actually see one of them. This morning it was a beautiful male Black-headed Grosbeak (Pheucticus melanocephalus).
We also saw some intensely colored American Goldfinches (Spinus tristis). We've had them in the yard on rare occasions in the past, but never got good enough photos to post on the blog.
It was nice of the birds to come to me, since I couldn't get out to them!

Just How Close Do You Want to Get? Western Bluebird on the Sabercat Trail

By color scheme alone they are one of my favorite birds. I'm just partial to blue that way, the darker the better (I've noticed this about favorite minerals as well: go azurite!). Western Bluebirds (Sialia mexicana) are not rare, but I don't see them nearly often enough.
I was walking on the delightful Sabercat Trail in Fremont the other day with my family, and a pair of Western Bluebirds were perched on tree stakes right next to the trail, and really didn't seem all that concerned about our presence. I was please to get a couple of up close and personal shots of both the male (above) and less colorful female (below).

Western Bluebirds are one of the arguments for not cutting down old snags and burnt dead trees. They are cavity nesters, but they don't have the ability to carve such nests like the woodpeckers. They instead let the woodpeckers do the work and take over after they have moved on. Bird boxes work well for them as well.
Such a nice moment on the trail!

Finding that First "Special" Bird: Bullock's Oriole on the Tuolumne River

I've thought a lot about the fact that I have become "that guy" on the Tuolumne River Parkway Trail. People can see me from a long way off, the guy in the silly-looking hat who always has binoculars and camera dangling off his shoulders, who can't walk in a straight line because his attention is always directed off to the side or above, essentially anywhere but the trail in front of him.
I have these conversations, sometimes imagined, sometimes real, where I feel just a little defensive and want to say "I'm not really a crazy birder, I'm just getting my regular exercise and I don't want to miss it if a really interesting bird or other animal shows up". But I actually am a crazy birder. But doing the same ritual practically everyday of walking at least two miles and counting birds along the way is not really that strange. Compare the strangeness of doing that with running on a treadmill in a gym every day. You run on top of the moving machine, and no scenery goes by. You maybe have a television on the side of the room to stare at, or you have earphones blaring music. To me that's pretty boring.
How cool is it that every single walk has the potential of becoming something wonderful? Like the dad said in Christmas Story, referring to his yet unopened grand prize, "Why there could be anything in there!" Sure, there are birds that one sees every single day throughout the year, the scrub jays, the doves, the mockingbirds, the starlings. But there are almost always little surprises, the birds you see only once in awhile: Spotted Towhees, Nuttall's Woodpeckers, Belted Kingfishers, or Cooper's Hawks. They add that little bit of spice that turns a mundane walk into an interesting one.

But then there are the migrants. They can only be seen during part of the year, some only during the winter, others in the spring and summer. New seasons bring the promise of that "first of season" sighting, the excitement of seeing a beautiful and spectacular bird after an absence of many many months. It's a neat moment that sometimes takes my breath away. It happened yesterday when I saw the first Bullock's Oriole (Icterus bullockii) of the new year. The bird is not totally rare, and I will probably see a few dozen of them over the next few months, but that first moment you realize what you are seeing is just plain special. Especially when they hang out long enough to get pictures.

There are many more such moments coming over the next few months and one never knows what day it will happen. There will be the first Hooded Oriole, Lazuli Bunting, Black-headed Grosbeak, Green Heron, Olive-sided Flycatcher, Phainopepla, Rufous Hummingbird, and about twenty others before the end of the year. Every single day is a potential adventure. 

Left unsaid of course is the even rarer potential of seeing a bird that you have never seen before, or one that no one in the county or state has ever seen. Climate change has resulted in some species ranging farther north than ever before, so the day may come when I will see something really special, like a Vermilion Flycatcher or Summer Tanager on the Tuolumne River. And that, my friends, is why I am "that guy" out there walking every day looking to the sky, instead of tromping on a machine at the gym.

A Merlin on the Tuolumne River, for the Second Time This Year

I didn't post about this back in January for plenty of reasons, too busy with school starting, and lousy pictures, but Merlins (Falco columbarious) have been visiting the Tuolumne River Parkway Trail this year. I saw one on January 6 which was gloomy and dark and not conducive for picture-taking, but the only other time was way back in 2018. But today was perfect weather, and the Merlin was cooperating by perching out in the open where I could get a few decent pictures.


Merlins are the 'Lady Hawks' of Medieval times, but they are actually falcons, and like other falcon species, they have been used by falconers for years for hunting and hobby purposes. They underwent a severe decline because of the use of DDT in the fifties and sixties, but they have recovered nicely since the pesticide was outlawed. 

It was a pleasant surprise to see one today.

New Bird on the Tuolumne River Trail! A Peregrine Falcon

It's always such a great moment when one sees a bird for the first time, or sees one the "home turf" for the first time. I had one of those marvelous moments today during my customary walk on the Tuolumne River Parkway Trail. There is a long-dead Cottonwood snag on the western part of the trail that is kind of a roadhouse inn for many kinds of birds. The high branches provide a wide-ranging view of the surrounding terrain so on a given day I might see American Kestrels, Ospreys, Red-tailed Hawks, Turkey Vultures, and on less common occasions, Red-shouldered Hawks and Merlins. The tree is also the nighttime roost for several dozen European Starlings, and home for a family of at least five Acorn Woodpeckers.
I was a bit pressed for time, and conditions were overcast and gloomy, so I wasn't expecting to see all that much, but as I approached the snag, I saw a bird larger than a starling but smaller than a hawk. I always assume it will be a Kestrel, but something seemed "off" about it. It was darker than expected, and I couldn't see the black face bars that distinguish Kestrels. I got the cameral out and took a few pictures, then tried to move closer, but alerted by a loud family on the trail, the bird bolted up the river. I thought it might be Merlin since I saw one there just a few weeks ago, but as I studied the photos on the camera I realized it wasn't that species either. I zoomed in and realized I had a Peregrine Falcon (Falco peregrinus). It is the first one ever reported on the trail, making a total of 150 species now known from the "Parkway" (it's not totally uncommon in the county, but the Tuolumne Parkway has only been watched carefully for the last five years or so)
Seeing the falcon reminded me of my other sighting last year. A friend of mine who works for the local irrigation district had alerted me to the fact that Peregrines had a nest in the cliffs above a small dam on the Tuolumne River at the east end of the county. I was given permission to enter the property to have a look and I wasn't disappointed. The falcons were busy discussing something or another, and were flying from perch to perch on the high rock cliffs.
I've only seen the Peregrine Falcons in a few other places, in Oregon and at the Sacramento National Wildlife Refuge. It was great to finally see one in my own "backyard".
