26 June Update

26 June Update
Back on the rarities road

My plan post-Texas was to fly to San Diego, hire a car for a week with a drop-off in Tucson three or four days later. The inspiration for the timing was a recently reported Nutting’s Flycatcher at the Bill Williams River Reserve in Arizona near Lake Havasu Arizona – home of the London Bridge, just over the California border. The broader plan was to pick up several so-called common species between San Diego and southeast Arizona, starting with Yellow-footed Gull at Salton Sea east of San Diego.

As so often happens, it was at almost precisely the time that I was flying from one region (in this case Austin) to another (San Diego) that a rarity showed up just behind me. This time it was Yellow-green Vireo near McAllen, Texas.

Getting back to recounting my SW trip, in addition to the YGVI appearance in Texas, at nearly the same time a White-eared Hummingbird was sighted at the Beatty Ranch at Miller Canyon, Arizona. Although this is an annual occurrence, it was still a pulse-raiser. But I was in California now, with what seemed to be a reasonable game plan - which I nervously decided to stick with. First stop was to the southern shore of the Salton Sea on Wednesday morning, where I watched a single Yellow-footed Gull picking at and devouring stranded fish, one bill-full at a time, impervious to any moral issues as the 20cm long fish tried vainly to escape in the receding shallows. The shoreline was littered with hundreds of desiccated fish, apparently victims of a lowering ‘sea’ level. There were plenty of other gulls lazing at water’s edge, as well as terns (Black, Forsters, Caspian), pelicans and shorebirds – including some scattered Snowy Plovers well above waterline.

With the YFGU box ticked, I drove through 115F temperatures to Lake Havasu City, Arizona on Wednesday afternoon. The aforementioned recent Nutting’s Flycatcher report was partially suppressed at the request of the reporting birders, citing concern about the safety of birders who might be tempted to look for the birds due to heat, snakes, and a confounding nature to the place.

I’ll admit that up until the time of the eBird report, Nutting’s Flycatcher wasn’t even on my radar. I was aware that the species was periodically reported from Bill Williams River Reserve, but it hadn’t occurred to me that it was actually resident on a year-round basis. Looking at the crazy number of eBird database reports for the species at the reserve now, I get it. Duh. As per Austin Powers “[it]’s the village bike baby, everybody’s had a ride.” I should have been chasing the bird months ago in cooler conditions. It didn’t take much research (with help from my southern California birding team) to learn that biologist Lauren Harker has kept tabs on these flycatchers for quite a few years, and had published information about accessing the area. When I contacted her she offered to help me find the flycatcher Friday morning – her only available time slot. Seeing it was only Wednesday however, and owing to my ADHD nature, I read everything I could find about the site (Bill Williams River Reserve), and prepared for a scouting effort on my own on Thursday morning. The access road was reasonably easy for a vehicle with good ground clearance – I rented a small SUV from Enterprise Rentals in Lake Havasu City. Arriving at the end-of-road gate at 5:30AM, I had a fantastic morning exploring the scenic (dry) river gorge and surrounding country, which is predominated by Mesquite scrub and occasional stands of cottonwoods. Conditions there are currently very dry, which may account for surprisingly few birds. Although I’m not recommending anyone else to make the hike, I had no trouble finding my way to my intended waypoints and returned to the car before nine owing to fast-rising temperature. Although I crossed tracks with a handful of Myiarchus flycatchers that morning (Brown-crested and Ash-throated), and thought at one point that I was ‘in’ when a particularly skulky, seemingly darker bird made an appearance. Unfortunately, the more I looked at my photos of this bird when I got back to the car, the longer the bird’s bill and tail seemed to grow – and the more elongate its form became. Alas, it was a Brown-crested Flycatcher.

Although I’d explored probably further than I should have, not being clear at the time precisely where the the previous guys had seen the bird (they were not specific). But with round two the next morning to look forward to – this time with Lauren’s help, I remained hopeful.

Lauren and I arrived at the end of the Planet Ranch Road about 4:40 Friday morning to maximise our pre-heat birding opportunities, with just enough emerging light to see our way upstream along the path/creek beds. It took about 45 minutes to get to ‘the’ spot where a Nutting’s Flycatcher had been seen in late April, and then again in late May, then presumably again last week. The area actually has a car park configured at it, where in years gone by it was possible to drive. The extensive vegetation is comprised mainly of a mix of dense thorny Mesquite trees/bushes and introduced Tamarisk trees with emerging poplar-like cottonwoods. Although I guessed there were very few flycatchers mixed in the thin morning chorus, Lauren’s skilled ears picked up at least four pairs of Brown-crested Flycatchers and at least a few singing Ash-throated Flycatchers. We waited for maybe ten to fifteen minutes – which seemed a lot longer at the time. Then I heard, in Lauren’s best matter of fact tone: “I just heard the Nuttings.” Winding the clock in my head back a few seconds, I reckoned that maybe I’d heard it too – but wasn’t sure.  Then, waiting another ten minutes, a Nutting’s Flycatcher sang more clearly – but just briefly. We relocated to a closer position and some time later heard it from the original position. This went on for about a half hour until two birds flew into a dense Mesquite tree, and from their calls Lauren somehow ascertained that one was an Ash-throated, but the other was a Nuttings. Before I could get binocs or camera onto them they were gone. But then, things went our way. A single bird flew to a nearby cottonwood and perched high before letting loose with periodic bursts of song. ID confirmed, I took my usual standard of low quality images, and gave Lauren the appropriate ‘high-five’. Great experience which included only a few bird sightings, but the Yellow-breasted Chat was great to watch, and we had a brief visit from a Bullock’s Oriole.  On the walk back to the car we crossed paths with what is now my favourite North American mammal (sorry my Gray Whale friends, I’ve moved on), a badger! First I’d ever seen – standard quality image below.

Lauren is obviously a terrific birder with a sensational ear, and a dedicated conservationist. She and her team are doing important survey work in the region, and despite some big challenges (like not enough water flowing into the reserve) I can’t help but be impressed by her optimism for the future of the bird fauna in some types deteriorated habitats. She cited a couple of examples of recent bush regeneration actions that have paid off. I wish her very best in her research and applied conservation work, and thank her for her help in my bird-chase.

Back to Lake Havasu to drop Lauren off, then a 3.5 hour drive to Phoenix to catch a late avo flight to McAllen to see about a couple of boisterous rogue vireos shaking up the National Butterfly Centre just out of town. The eBird reports indicated that there were at least two male Yellow-green Vireos on the National Butterfly Center grounds, and that the two appeared to be competing for the butterfly park kingdom, with constant singing and occasional chasing of one another. From the moment I stepped out of the car at the well treed far end of the park – and throughout the hour or so that I stayed, the two male Yellow-greens almost never stopped singing, usually maintaining a distance of 30 metres or so – but occasionally swooping in on one another to keep the tensions high. I never saw physical contact between the two, and both made occasional hops and flutters to score insects in the tree-tops. One of the guys working at the park said that he thought there was a female in the area as well, though I never saw her.

I really like south Texas, but with the main game always at the fore, I cut my stay as short as possible to get back on the road. I wished that I could have stuck around for another shot at Red-billed Pigeon, but that mission will have to wait a bit longer. Still, I’m very excited about the wider prospects for the next week or two, and will hopefully have something interesting to put on the blog in a few days.

Quick summary of SE Arizona – unfortunately the White-eared Hummingbirds haven’t been around for a couple of days, so after finding two year-birds – Botteri’s Sparrow and Sulpher-bellied Flycatcher, I’m tearing myself away from this beautiful place.

Following is a summary of my coded bird sightings for the year so far, which really tells the story of my soon to end Big Half Year of birding. Accumulating this list of rarities has consumed most of my energies (and savings!) for a period that now seems like six years – not a mere six months. Maybe next blog entry will be some summary stuff and review of my strategy for that period – watch this space. Photos for current blog appear below the list – scroll down.
