As I’ve commented in earlier posts right here, I think about myself very lucky to have an excellent (and nonetheless rising) variety of highly-qualified birders with whom I can seek the advice of and, generally, fowl. All are Mexican. Most, however not all, reside outdoors of Morelia, however someway we handle to get collectively — or I seek the advice of with them on-line. Fairly just a few of them are biologists.
The primary week of July, the celebs aligned, and I used to be capable of fowl with two of those biologist pals. Alberto Lobato, an ornithologist from the jap facet of Mexico, can be in Morelia, and will we go birding? Now, Alberto is one thing of a celeb. He began talking at birding conferences when nonetheless a teen. His YouTube channel, Crónicas del Chivizcoyo, presently has nearly ten thousand subscribers. And his eBird self-description comprises the next superior rationalization for his nickname: “I’m the Chivizcoyo (one thing like “I’m Batman” however higher).” (Really, Chivizcoyo is a typical identify for Mexico’s legendary Bearded Wooden-Partridge.) Within the mild of all this, I wanted to up my recreation.
Shortly afterwards, my good birder buddy Nacho, instructor of botany at a prestigious native college, advised me he was on trip, and want to fowl with me. So now, we had a celebration! However the place would I take such an illustrious firm?
Luckily, I had avery particular fowl we may all go search. Early July is correct in the midst of month-and-a-half the place I’ve seen the Sinaloa Martin. (I additionally noticed it as soon as in February.) And what’s so particular concerning the Sinaloa Martin? Properly, you could possibly search for different North American swallows on eBird, for comparability. eBird studies having obtained some 4.8 million Tree Swallow observations, 1.25 million observations of the Cliff Swallow, 1.8 million of the Northern Tough-winged Swallow, and 1.15 million for the Purple Martin. Go a bit extra unique, and also you drop to 75 thousand observations for the Mangrove Swallow, or solely 7.3 thousand reported sightings of Central America’s Black-capped Swallow. The Caribbean Martin, a detailed relative of the Sinaloa Martin, is available in at (as I write) 17,102 observations.
And the Sinaloa Martin itself? The day earlier than we went to Paso Ancho, it had been reported a grand whole of 134 instances — and 6 of these have been mine, all from that very same city. Eighteen studies included pictures — and, as soon as once more, six of these have been mine. Assuming that a number of of the observers concerned had made a number of observations, that in all probability represents solely round 100 folks having ever reported this species, regardless that it breeds in a rustic bordering the USA.
Male Sinaloa Martins appear to be Purple Martins. Besides the place they don’t (the sharply delineated white underparts).
This fowl had been turning up for me ever since 2015, and I’m fairly positive I’ve by no means seen it with out an early-morning bathe previous the outing. Luckily, 2022 is popping out to be a banner 12 months for rain in central Mexico, and we had a lot of rain in Morelia the evening earlier than our journey. As we drove down into the warmer, drier lowlands, there have been nonetheless many moist spots on the highway. So I had hope.
And but, we didn’t handle to make it to Paso Ancho, a minimum of not instantly. That’s as a result of we occurred to search for at an influence line, and see a critical variety of Swallows perched there, with extra flying above. May the be? They may!
Because it occurs, Alberto/Chivizcoyo had seen his one remaining Mexican Swift species, the White-fronted Swift, two days earlier than. (Mexico boasts ten Swift species.) And now, he was seeing his last Mexican Swallow species, out of twelve. In fact, it was additionally a lifer for Nacho, however he’s a brand new birder, and it’s straightforward to provide him lifers. That’s one of many issues that I like about him. As I recall, he picked up eight lifers that day alone. As for me, I used to be relieved to not have taken all of them that means on a wild, properly, Martin chase.
Because it occurs, we noticed some 45 Sinaloa Martins that day. I haven’t checked all of the eBird lists one-by-one, however that is nearly actually the most important quantity ever noticed in a single day. Simply by taking a look at these photographs, you’ve got now seen greater than nearly any mortals have:

A few of the group from website #2
So many issues are unknown concerning the Sinaloa Martin. Nobody is aware of the place they spend winters. Till not too long ago, their migration route was additionally unknown; however now, a transparent route down south-central Mexico might be seen by stringing collectively a number of studies. Paso Ancho appears to be alongside that route. However there are particular points that counsel that this city isn’t an early cease alongside their migration, however quite part of their summer time breeding vary. For instance, I’ve noticed this Martin in Paso Ancho all the way in which from the final week of June to the primary week of August, which might be a very long time for a migrating inhabitants to be current. Additionally, on this outing we noticed a lot of juvenile-to-immature Martins. A lot of them have been nonetheless begging for meals from adults:
Each immatures
This immature begs for meals from an grownup. It has no disgrace.
Merlin has already taken a stance on this thriller. When I discovered my first Sinaloas, Merlin confirmed their vary as stretching from Mexico’s southwestern state of Jalisco to the northwestern state of (shock!) Sinaloa. Now, seven years later, the breeding vary is proven to incorporate… Paso Ancho. Nonetheless no phrase on the place they winter, although. Sounds to me like an excellent topic for a doctoral thesis, when you’re into these issues.
In fact, regardless of how a lot one desires to see a single species, you possibly can’t ignore different particular birds that flip up. The Pink-breasted Chat is one other tough (and exquisite, and fairly musical) endemic species of Mexico’s southwest. This one presently has just one,879 observations on eBird. I used to be delighted to seek out one proper alongside the highway, for the reason that different website the place I’ve seen it within the Paso Ancho space entails a protracted stroll in a scorching local weather.
Additionally, far within the distance, there have been Swifts. The 2 Chestnut-collared Swifts have been nearly to be anticipated right here. However the single Higher Swallow-tailed Swift, with a colour sample like a flying penguin, was a uncommon deal with certainly. This can be a “massive, spectacular swift” (eBird’s phrases, not mine, though I agree, having seen it as soon as up shut). And it’s not reported way more than the Sinaloa Martin, with solely 879 observations registered. So I refuse to really feel disgrace for the next picture:
Oh… all proper… perhaps only a little bit of disgrace. I’ll shut as a substitute with a bonus Becard picture:
