Not only is the 10 inch Altamira Oriole the largest of the six resident and two migratory oriole species in the Yucatan Peninsula, but it also produces the longest pendulous nest of those species. Usually the nest dangles from tips of high branches or even utility lines. These hanging baskets, 16-26 inches in length, are easy to see along the roads in the peninsula.
Two years ago I saw the beginnings of this nest where the female used plant fibers to construct the woven pouch. She interlaced each plant strand back and forth thousands of times using only her beak. This female architect took three weeks to finish it.
Since that nest wasn’t destroyed by rain or weather after the first use, the monogamous pair continued to upgrade it. This year the female adorned that pendulant cup with her mouth-to-mouth reconstruction with purple and lavender threads and a lavender ribbon! How’s that for a cup-uppance to other orioles?
When I first saw this colorful creation this year, the orioles had chicks. (I never saw how many hatched.) Both parents brought insects to their young. Each parent may wait on the just-fed chick to produce a white, membrane-covered, fecal sac. The parent then carries this “disposable diaper” away from the nest to clean their basket home. Also, that action may keep the young healthier and possibly reduce an odor that could attract predators.
Even the tiniest, single feather can be removed during house cleaning. Maybe each parent becomes a “feather duster”.
Sometimes I only saw a parent bird once in an hour. In the meantime an unexpected visitor searched this elongated masterpiece for insects…the Cinnamon Hummingbird.
Something else that surprised me was how fast each adult flew into their nest. I’d see one approaching and start depressing my camera shutter before it ever reached the nest. How could a speeding bullet of feathers fly into a nest at a 90 degree angle without plunging or destroying the top of the nest? It didn’t seem to slow down. I shot at 2,000th of a second and still missed it!
Other times, Mom and Dad Oriole were so fast with their special delivery of insects to their brood, they almost flew into each other.
Mayas call the oriole, Yuya or Yuyum. Maybe that’s how the chicks respond when they are fed. Yu-yum or Yu-yummy!
Go outdoors and ingest your own nature magnificence!
