Those Tropical Kingbirds! A Fun Coincidence...

Tropical Kingbird, Florence Oregon, Nov. 2022
In October of 2020 during the height of the Covid epidemic, I was beginning the habit of walking the Tuolumne River Trail in Waterford every day for exercise and birdwatching. I saw many interesting birds, over 120 species that year, but on that day in October, the bird I saw was memorable, although I didn't know it in that moment. What I thought I saw was a Western Kingbird. It was a bird that should have been far away in Central America, being a long-range migrant. It was wildly out of season. So I took pictures to document it, and sent copies to some local birders. I was told immediately that it wasn't a Western Kingbird at all, but that it was instead a Tropical Kingbird (Tyrannus melancholicus), a bird I hadn't even heard of before, as it was a bird more native to Mexico and southern Texas. What's more, it was the first sighting of the species ever in Stanislaus County. So that was all very exciting at the time.

Jumping forward to the present day, I was up north in Oregon, in Florence for Thanksgiving. Although there was little time for intense birding, I kept my camera close by and while walking through Old Town Florence, I saw a bird on the wires above that seemed a bit out of place. It was more yellow than the species I was expecting to see. I snapped the picture above and realized it was a Kingbird. I checked for the tail markings that would have meant Western Kingbird, but they weren't there. Cassin's Kingbirds simply aren't found that far north, and it didn't have those tail markings either. I knew that despite their rarity, some Tropical Kingbirds were known to range pretty far north along the coast. So I checked the eBird records and found that one or two had been seen in the immediate vicinity over the last few weeks. I had found the second Tropical Kingbird I had ever seen!
Tropical Kingbird at CSU Stanislaus, Nov. 2022
I got back to the motel and reported the bird and checked my email. Much to my surprise I found that a Tropical Kingbird had been sighted in Stanislaus County that very day! It was on the campus of CSU Stanislaus, where I teach a couple of courses. It was only the second sighting ever in the county, and it stayed in the area long enough for half a dozen birders to catch a view. Being six hundred miles away, I felt I had little chance of getting a look, but I headed down there today to teach my classes. Wouldn't you know, there it was right outside the Science Building. I got just one lousy shot before it flew off, but I got to see the rare visitor.

An interesting convergence of sightings...

The Tale of Really Lost Bird: A Tropical Kingbird (probably) on the Tuolumne River Parkway Trail

There was this bird this morning. It was way out of place, but for more reasons than I realized at the time. I'm really familiar with our summertime visitors from Central America, the Western Kingbirds (Tyrannus verticalis). They love our local prairies and I see them all the time by the dozens when I drive around. But they are a migrant and they spend winters down in Mexico and Central America. So imagine my surprise when on the 3rd of October I see a familiar yellow and gray bird on the powerline munching on a dragonfly. I knew it was the wrong time of year, so I pulled out the camera to get some documenting shots for my eBird post.

But as I was snapping the  photos, I  realized something was missing. Western Kingbirds usually have a white strip on the flanks of their tail feathers, and this bird didn't have those. So in my intimate knowledge of the local bird possibilities (rolling of eyes allowed here), I thought of a Cassin's Kingbird (Tyrannus vociferans). This would be kind of exciting because although they've been found in other parts of the county (even the MJC campus), they've never been sighted on the Tuolumne River Parkway Trail. So I took more pictures looking for the white-tipped tail feathers that identify the Cassin's. 

They weren't there. So that was kind of quandary, but I have learned that late in the season the birds feathers can become worn with use and the white coloration might not be visible. I reported the sighting on eBird as an out-of-season Western Kingbird and sent the pictures to a few birders for advice, and moved on to other things. It bothered me though that I couldn't nail down the identification.

A few hours later I get an email telling me that I had photographed what is most likely a Tropical Kingbird (Tyrannus melancholicus). This is even more exciting because not only has it never been seen on the Tuolumne River, it's never been seen in the entire county! This is a bird that is native to South and Central America, Mexico, the southernmost tip of Texas, and the southeastern corner of Arizona. Vagrants wander into California every year, but they stay almost entirely along the coastal zone. 

I've been wondering where this bird came from, and it occurs to me that this could be one of the sad effects of the California wildfires. I can imagine birds being driven from their habitats by these terrible and extensive fires, looking for food and water. That's my hypothesis, in any case. 

The only reason it isn't absolutely, positively a Tropical Kingbird is because there is a practically identical bird called the Couch's Kingbird, which has been seen in the state of California only about three times. The only real way to tell them apart is by hearing their song, which is very high-pitched, meaning I couldn't have heard it even if it was singing. Understandably there will be a group of birders on the trail tomorrow hoping for a sight (and a listen). I hope it's still there!
