New Yard Bird: Ruby-crowned Kinglet

Bird nerds rejoice at a variety of things. They might be dorky bird-counting milestones or they may be things that have larger consequences.

Yesterday I celebrated "yard bird" number 35. This milestone may qualify on both counts. I had not seen a ruby-crowned kinglet in my yard in the 6 1/2 years we have lived here, so it was fun to see it. Birders on their local "patches" keep track of such things. It's just a birder thing.

But where did I see it? It was on a blue palo verde (Parkinsonia florida) and a desert hackberry (Celtis pallida) that I planted about 1 1/2 years ago. This native tree and large shrub, respectively, have grown a bit since I planted them.

Apparently they have matured to the point where they provide places for native insects to live. Many of our native birds eat insects. I have seen verdins hopping around in these plants several times. Verdins eat insects almost exclusively. The time that verdins now spend foraging in these plants suggests they are finding something to eat.

Ruby-crowned kinglets, which spend the winter in our region, also eat insects. The one in my yard spent enough time in these plants to suggest that the native plants I planted were supplying it, too, with food.

The kinglet also spent enough time there for me to get some photos. Enjoy.

Ruby-crowned kinglet. Note gray-green color overall with yellow highlights on the wings, white wingbar, a dark bar behind the white wingbar, and, just slightly visible, a little white just in front and behind the eye. This bird is only about 4 1/4 inches long. The plant is a desert hackberry.

This photo of the kinglet is blurry but it shows the white in front and behind the eye.

Here is a verdin for comparison. It is only slightly longer, at 4 1/2 inches on average. It too is in the desert hackberry. Verdins are common visitors to our yard.

Back to Flog the Blog

I've taken a couple months off from the blog. I traveled to Colorado and then briefly to California, and handled some family responsibilities. The trips boosted the overall total number birds seen over the year a bit (see numbers to the right).

But now I'm ready to get back to exploring Tucson metro birds. So it's back to work--and good timing too. This morning I saw a western kingbird from my back yard. First time I've seen it in the neighborhood, let along from the yard. That's a "twofer"--yard list and neighborhood list!

Western kingbird on the wire over the alley this morning. (Watch those wires folks!)

There are some rarities being seen about the area, including a tricolor heron at Reid Park. But as usual I'm more interested in more common stuff. Though that's not to say I won't go off looking for the heron!

Next time a post about how the lesser goldfinches seem to be enjoying my back yard, in spite of the fact I don't have a feeder for them.

At My "Whits" End

I haven't been able to meet the challenge of writing at least one blog post per week, so I am a few weeks behind in the news. Around the beginning of May I started to hear brown-crested flycatchers in my Tucson neighborhood (Palo Verde neighborhood). You typically hear their "whit" calls plus other "gurgles" (as I, idiosyncratically, call them).

I set out one morning with a camera and the dogs in tow to see if I could get a photo. This is the best I could do--it's as much a photo of mesquite as it is flycatcher. I'll keep trying, but at least you can see the darker, brownish crest, the gray throat and breast, the yellow belly and the warm, orangish-brown color in the wings. Here is more information about brown-crested flycatchers.

What's in your neighborhood? Just go out and look!

The Yard Birds

Once you are paying attention to birds, you recognize when something new shows up. According to my records on ebird.org, before Saturday May 10 I had seen 30 bird species in, or from, my yard.

Again, I'm not out to set records. I don't have time to sit around the yard every morning and observe every bird that comes by. This is the effort of a reasonably good birder that pays attention some of the time--an effort I think many people can identify with.

Green-tailed towhee
Well, I had been trying to get some yard work done, little by little, in the cool of the morning. I was in the back yard when I heard what I thought I might have heard the buzzing call of a lazuli bunting. That definitely would have been a new yard bird. Plenty of them come through town in spring migration but never had I seen one from my yard.

I went inside to get a camera just in case. But after a few minutes it was clear there was no lazuli bunting. Maybe it was just one of those house sparrow sounds I had heard, or maybe it was "the bunting that got away." But as I walked back toward the house a bird flew into the yard that was shaped like a towhee--kind of like a sparrow but larger, lanky, and with a long tail. As it foraged on the ground for treats, including below the bird feeders, I saw the reddish cap, the gray underside, white throat and the greenish hue, especially on the tail.

Green-tailed towhee is an attractive bird that is found around the Tucson basin in the winter--though usually tangles of native trees and shrubs and usually not back yards. By some time in may they leave for nesting sites in the mountains or much farther north. It was nice to host one in the yard, if only for a few minutes.

Recent Sightings

Wilson's warbler on the cover of the April-
June 2014 Vermilion Flycatcher magazine
In April Wilson's warbler's stop in our yards and our natural areas. All they want is some bugs. Our native trees and plants, especially flowering mesquites, provide all they need.

Dr. Charles van Riper has studied Wilson's warbler migration. He found that once having found a bountiful area the warblers may stay in that area--maybe in the very same tree--for two or three days eating insects before moving on. You can find more on this in the April-June 2014 issue of Tucson Audubon's Vermilion Flycatcher magazine.

Watch your blooming mesquites in April and early May!

My back yard has a large mesquite and in late April it was in bloom. But I had never seen a Wilson's warbler there. On Sunday April 27 I slept in. It was the day after my birdathon (see previous blog entry) and I had been awake for about 22 hours on Saturday. But by 10:30 a.m. I was up and sitting in the back yard, reading the paper and eating breakfast.

Well, when you have been watching and counting birds for around 19 hours the day before, you can't just turn it off. I made mental notes of the birds I was seeing and hearing in the back yard. Then I brought out the laptop and began entering a checklist what I was seeing into eBird. By 11:30 a.m. I had seen 14 species--pretty good for having just sat there for an hour. One of the last birds to show up was a Wilson's warbler. True to form, it was foraging for insects among the mesquite flowers.

It's the Most Wonderful Time of the Year

The Christmas song is wrong. The most wonderful time of the year is spring!

In southeast Arizona migration is wonderfully drawn out, with some migrants appearing very early in the year. Many of the other early migrants are in place looking for nesting opportunities by mid March. More continue to arrive in April, some arriving to nest and others just passing through. By the end of April we've reached one of the two points of the year with the most avian diversity.

I've neglected my blog posts. Work and birding take up a lot of time this time of year.

On April 26 my Team did our Birdathon fundraiser for Tucson Audubon Society. In this fundraiser, sponsors pledge per bird species and teams try to see as many species as possible within 24 hours. The end of April is a nice time for it, not only because of the available bird diversity, but because the weather is usually very nice. In comparison to August, the other height of bird diversity, birds are more vocal in spring--singing to define their territory and attract a mate. This makes them easier to find.

We decided to limit the area where we could go birding to Tucson and its immediate vicinity. This would make it an opportunity to show people Tucson's avian riches. It would also mean that we

would be driving less and birding more--more species per gallon of gas! We decided we would stay within a 20-mile radius of Reid Park. This still gave us a lot of latitude--the top of Mt. Lemmon, the east, south and west sides of Tucson, Catalina State Park were all inside the circle.

We met at 1 a.m. to look, or rather listen, for owls in northeast Tucson. We moved up the Mt. Lemmon highway to find higher elevation owls and other night birds like Mexican Whip-Poor-Wills. It got windy and it was hard to hear anything but dawn came and we birded for hours in the

mountains seeing many, though not all, of the species that can be seen up there.

We came down the mountain and visited an area along Tanque Verde Wash, getting lucky and finding the gray hawk that has been in that area. Other stops were Reid Park, University of Arizona Farm, Sweetwater Wetlands and Crossroads Park in Marana.

When all was said and done we had seen 134 species. We feel we've set the baseline for the number of species that can be seen in 24 hours in

this area. We hope others will take us up on a big day competition in this circle.

What a glorious town! There are so many kinds of birds just a short drive away. I hope you enjoy them as much as I do.

More species--some of the late migrants--show up in our region in May. I'll be watching for those in the days to come.

What's in Your Neighborhood? The Garden District Tries to Answer that Question

The Garden District, the next neighborhood east of mine, got wind of my effort to promote urban birds and birding. They asked me to do a bird walk. I agreed and Meg and Kris, from the neighborhood association, arranged for me to lead a walk yesterday (Saturday) morning at 7 a.m.

Let me know if this is something you would like to do in your neighborhood!

I went over about 6:45 a.m. and met about 10 residents. Our hostess, Lisa, set out a great spread of coffee cake, orange juice and strawberries. Lisa's partner Michael, a biologist, was quite knowledgeable about neighborhood birds--I could tell right away he'd be an asset as we walked around the neighborhood.

A big thank you to the Kris Yarter of the Garden District for supplying the next two photos.

We set out through the neighborhood seeing plenty of house finches, house sparrows, mourning doves, white-winged doves and lesser goldfinches. When we arrived at a large, corner lot with a lot of native vegetation, the first thing we spotted was not a bird but a swarm of bees that had spent the night in a blue palo verde along the street. We gave it a wide berth and learned later that it had moved on later in the day.

Other finds were made here including an early-blooming saguaro that was attracting birds and bees.

Saguaros provide food and nesting opportunities to birds. It's not always the woodpecker holes that provide a place to nest. This rotten section of a saguaro arm made the perfect nesting spot for this dove.

I've also heard of Lucy's warblers nesting in tiny rot-holes and of course some large raptors like Harris's hawks and caracaras have been known to build their nests in saguaros.

Later we saw vermilion flycatchers in two different places. Both times we saw evidence of family life. I knew about one at the elementary school yard and on this occasion we found both the adult male (pictured below--an earlier photo of the same male) and an immature individual, apparently a fledged young-of-the-year. Also, in a back yard along an alley we found a male feeding a female that was sitting on a nest!

Here's a photo of the male vermilion flycatcher at the school yard I took a while back.

In the same alley from which we saw the flycatcher nest we heard incessant singing of a Lucy's warbler. It turned out there was a pair of them acting as if on a nesting territory. I want to go back and track down whether there is a nest in that area. I thought it was rare for them to nest in residential areas, so I want to follow up. In the same alley--let's call it the "magic alley" since we saw so much there--we saw an Abert's towhee fly up to a fence, sit for a minute, and then disappear out of sight.

Back at Lisa's house after the walk, an Abert's towhee showed up at her seed feeder. Michael said that although they've come in the past, it had been some weeks since the last sighting. Today Lisa emailed that they are still coming to the feeder, and that she was attributing that to my influence! Perhaps I can take credit for heightening their vigilance in observing the feeder. In any case it was a successful morning of meeting new neighborhood birders and enjoying nature in a residential setting.

Here is the complete list of species seen during the walk:

Cooper's Hawk (Accipiter cooperii)
Rock Pigeon (Feral Pigeon) (Columba livia (Domestic type))
White-winged Dove (Zenaida asiatica)
Mourning Dove (Zenaida macroura)
Black-chinned Hummingbird (Archilochus alexandri)
Anna's Hummingbird (Calypte anna)
Gila Woodpecker (Melanerpes uropygialis)
Empidonax sp. (Empidonax sp.)--probably a migrating cordilleran or pacific-slope flycatcher
Vermilion Flycatcher (Pyrocephalus rubinus)
Verdin (Auriparus flaviceps)
Cactus Wren (Campylorhynchus brunneicapillus)
Curve-billed Thrasher (Toxostoma curvirostre)
Northern Mockingbird (Mimus polyglottos)
European Starling (Sturnus vulgaris)
Lucy's Warbler (Oreothlypis luciae)
Abert's Towhee (Melozone aberti)
Great-tailed Grackle (Quiscalus mexicanus)
House Finch (Haemorhous mexicanus)
Lesser Goldfinch (Spinus psaltria)
