{Etymology Corner} Another local name for the bird is bolsero dorsilistado, which translates to Streak-backed Purse maker, which refers to these birds really cool looking nests. These birds (along with several others) construct what is called a penduline nest, or a woven structure made from grass and other foliage that hangs from a tree branch. These are really cool looking. Here is one such nest, also from this trip to Costa Rica.

§A Scream of Swifts§ (Ok, I know, I know, these are Martins, not Swifts, and that's not even the same family (SOMEHOW), but I hadn't heard 'scream' as a term of venery before and I thought it was neat. Guys, the well is DRY on this bird, there are no other interesting facts about it. If you know anything about swallows or swifts, you know everything there APPARENTLY is to know about these birds. Ok, fine, fine, here's something-)

~True Bird Fact~ They can't walk, their little legs are only for perching. See!! That was the best I could do. That's barely interesting at all and something you probably would've assumed just looking at this thing. This bird blog was held up SIGNIFICANTLY while I tried to come up with something to say about this Gray-breasted Martin, which, BY THE WAY, this might not even 100% be, because Swallows are hard to ID. So LAY OFF!

Turquoz-browed Motmot (momoto cejiceleste) aka. Torogoz aka. Guardabarranco (lit. Ravine-guard) aka. Pájaro reloj (lit. Clock Bird)

National Bird of both El Salvador and Nicaragua

{Etymology Corner} I think we got a famous one here ladies and gentleman. It's always a good sign when a bird has like 6 plus names, and they're all really expressive and beautiful, and that's the situation we have here. In El Salvador, he's called Torogoz, which is a reference to the sound he makes (you be the judge). In Nicaragua he's called Guardabarranco (lit. Ravine-guard). In the Yucatán, he's called Pájaro reloj (lit. Clock Bird, for the way he moves his tail). And in Costa Rica he's called Pájaro bobo (Foolish Bird) for his comfort around humans. That's the good stuff!

~True Bird Fact~ So, that tail- it's referred to as 'racketed' and serves a couple of purposes. First, they use it for sexual selection- i.e. a male with a long tale is a more desirable mate. But interestingly, they also use it to communicate with predators (!). They wag their tail back and forth, like a clock pendulum, to signal to a predator that they have been observed, and that pursuing them would be pointless, because they will fly away if approached. This is called a 'pursuit deterrent signal'.

~Real Bird Myth(?)~ Look, I don't know what to trust anymore in regards to the internet. But there are lots of claims that the Motmot is a significant bird in Mayan cultural tradition (and why not, look at it!). Most of the stories I found were on travel websites, and they all had a theme of how the bird lost most of it's tail feathers, leaving only the aforementioned 'rackets', usually as a result of arrogance. Here's my favorite one of this genre, which I totally can't vouch for as legit, from this website.

The motmot’s Mayan name is toh, and it features in local legend and lore. According to one story, the motmot liked to meet his fellow royal birds and spend the day telling stories and feasting on insects while other birds were working. He was such a beautiful creature and so proud of his glossy tail and plumage that it made him arrogant and overbearing.
One afternoon, when black clouds were massing on the horizon heralding the approach of a storm, Oc, the king vulture summoned all the birds to a meeting and they decided to build themselves a shelter. Chujut the woodpecker, Panchel the toucan, Mox the parrot and Xtut collected timber, Baax the chachalaca and Cutz the wild turkey carried the heaviest branches and the hummingbirds collected grass, herbs and leaves for the roof. Other birds gathered fruit and seeds to tide them over the storm. Only the motmot refused to help, saying that he was an aristocrat, not a worker.
When the storm burst, the motmot found a crack in a stone wall that he thought would be a good place to hide. He crept in and went to sleep without noticing that his elegant long tail was still out in the open.
Much later, the motmot woke up and emerged from his shelter to sing in the sun like the other birds. He was astonished to find that all that was left of his beloved tail were two bedraggled and naked barbs with a small clump of feathers at the end. The wind and water had done their worst. Horrified, realized what a fool he had been. Pride soon got the better of him and he decided to shun his former companions for fear that they would mock him. He flew off into the depths of the forest and dug a hole where he hid until this very day. He still keeps to himself; perching on branches overlooking cenotes where he swings his long tail from side to side incessantly like the pendulum on a clock.
