Happy Halloween to all you nature lovers out there! Its been a rainy past week here in the Lower Rio Grande Valley, and the thorn forest at Quinta Mazatlan was lush and humid – a good example that we are indeed a tropical forest.
As always, we took time to stop and look for some of our resident Common Pauraques. They truly are common birds here in the Valley, but because they are so well camouflaged and forage at night, I don’t think Valley locals are aware of how many there are. The best way to tell if you have a pauraque in your area is to know the sound of their call.
Out of curiosity, I wanted to look at the annual frequencies of the four hummingbird species we regularly see at Quinta Mazatlan. Buff-bellied Hummingbirds (gray line) are the most common, becoming reported on 80-90% of eBird checklists in the fall. Only small numbers of Ruby-throated, Black-chinned (note the uptick of frequency in the summer, as this is a breeding bird), and Rufous hummingbirds are reported in the winter months.
I saw two Hermit Thrushes today visiting one of our water features. These birds winter across the southern United States and down into Mexico and Central America. They’re not commonly seen wintering birds (probably because of their liking of thick forest understory), but they are present in every year.
Out in the more open habitat of Ebony Grove (where I also had a Pyrrhuloxia), I saw one of our more common winter birds – an Eastern Phoebe. These flycatchers often bob their tails, and make short sallies (flights) out from their perch to catch insect prey. Because of their relatively dull coloring, I often get “fooled” into looking more closely at them thinking they may be a different species. Despite being common (and tricking me), they are pretty little birds and have a sweet call.
As many of you know, I tend to get happily distracted on our Songbird Strolls by all other amazing flora and fauna our parks hosts. This morning I decided to try to re-locate a South Texas and Florida specialty vine, Tournefortia volubilis. I was inspired by Doug Tallamy’s recent talk here at Quinta Mazatlan, and all the wonderful native plant experts that came to Planta Nativa. I did manage to find at least one individual plant, and though I searched for a Saucy Beauty moth (another South Texas specialty), I couldn’t find any this time.
As always, the full bird list is below. Have a great weekend!
