April saw the return of Field Guides to Big Bend National Park, the scenic Davis Mountains, and the beautiful Texas Hill Country, providing an opportunity to explore a diverse range of habitats and experiences. The trip began in San Antonio for a quick pickup and departure west to Del Rio. Our arrival was met with dramatic, storm-filled skies and a few of our first species, including Lesser Nighthawk. Our first full day began with cool temperatures and gloomy skies, but we saw a multitude of species around the Rio Grande. These included a few south Texas specialties, such as Long-billed Thrasher and Olive Sparrow, as well as Couch's Kingbirds. After lunch in Del Rio, we were distracted temporarily by a flooded field full of various shorebirds, Franklin's Gulls, and dozens of Yellow-headed Blackbirds. After picking through these, we continued on westward, making a stop at the mighty Pecos River overlook. After taking in the views there and another brief birding stop in Langtry, we headed on to Big Bend National Park.

Our first full day in Big Bend National Park was a bit cool and misty. The views were dramatic with clouds clinging to the the peaks, spilling over Casa Grande. We decided to visit the water treatment plant's overflow area, a marshy area with standing water, attractive to species in an otherwise parched landscape. We managed to connect with a male Lucifer Hummingbird and Varied Bunting along with others. That afternoon we visited Panther Junction, the terrific Fossil Exhibit, and finally Dugout Wells. While things were kind of quiet at the wells, Alex spotted an Elf Owl that had started to call spontaneously in the daylight.

Our second full day included a drive through the park southeast to Rio Grande Village and Daniel's Ranch. Our our way down there, we saw what appeared to be a nightjar sitting on the median strip of the road. Backing up for a second look, sure enough it was a Lesser Nighthawk that must have been stunned by traffic. Alex moved it off to a safe spot and we continued on our way to the river. Surprisingly, the black hawks were not evident around the nest site, so we headed over to Daniel's Ranch where we connected with Gray Hawk and a surprise Least Grebe on one of the small ponds there. A singing Lucy's Warbler was a treat. As we were wrapping up there, Eric spotted the Common Black Hawks flying west over the river! Less exciting but surprising was a Gray Catbird in the quieter section of the campground. That afternoon we visited the Old Sam Nail Ranch, a tiny oasis in the middle of Chihuahuan Desert. It was pretty quiet except for Bell's Vireos and Yellow-breasted Chat. We did have a nice though brief encounter with a migrant Virginia's Warbler there. We decided to head on to Cottonwood Campground after this. In addition to another pair of Gray Hawks, we enjoyed seeing a couple of nests, Black-chinned Hummingbird and Vermilion Flycatcher. Our only Green-tailed Towhee was here.

Our third day was the big hike day. We headed up the Pinnacles Trail roughly three miles to the first accessible Colima Warbler spot. Early on, we lucked into a great mammal sighting, a Black Bear attempting to topple an agave stock. Arriving at the Colima site, a bird was singing persistently, but it took some patience before the bird moved to a spot where it could be easily seen. But great views were eventually had by all. At this point, Alex continued on to Boot Spring with Stacey and Heather, Eric hiked with a few to the top of the Pinnacles, and I hiked back with those wishing to turn around at the three mile mark.

On our last morning in the park, we decided to pay a second visit to the water treatment plant, which was nice with about 36 species seen. Then it was off to Alpine for lunch and then to the Davis Mountains for an evening searching for Montezuma Quail. On our way there, we spotted a few Chihuahuan Meadowlarks, a recent split from Eastern Meadowlark. Our evening search failed to find quail, but we did pick up some interesting birds, including a huge flock of Pinyon Jays and a couple of Lazuli Buntings.

The next morning we had a nice picnic breakfast in the Davis Mountains with an exciting sighting of Montezuma Quail on the way to our breakfast spot. At the picnic site we enjoyed a pair of Gray Flycatchers and both Hepatic and Western tanagers. Then it was on to Lake Balmorhea, a spot that there never seems to be quite enough time to explore. The south end of the lake was hopping with birds. We ended up seeing 61 species of birds there! Then came the long drive east to the Hill Country and Utopia, along with a nice dinner and pie and the Lost Maples Cafe.

The next morning was spent at Lost Maples State Natural Area, one of the most amazing birding sites around. A splendid mix of east meets west, and host to such desired species as Golden-cheeked Warbler, Black-capped Vireo, Louisiana Waterthrush, Tropical Parula, Acadian Flycatcher, and Yellow-throated Warbler. We ended up with close to 50 species during our morning there. That afternoon, we visited a couple of spots north of Utopia. Field and Clay-colored sparrows were among the highlights there.

Our last full day of the trip found us heading west toward Bracketville to seek out Gray Vireo, Dickcissel, and others. After a bit of searching we did connect with the vireo as well as another great view of Black-capped Vireo. A pair of day-flying Common Nighthawks were also a treat. Then we explored Fort Clark Springs a bit. Here Yellow-billed Cuckoo, Great Kiskadee, MacGillivray's Warbler, and Indigo Bunting were among the highlights. We made a heat-of-the-day visit to Cook's Slough that was unsurprisingly quiet, and then it was on to the Frio Bat cave for our picnic dinner and evening with the free-tailed bats emerging from the cave. Thanks to Christine and Travis for providing the yummy BBQ feast!

Then it was time to say our farewells back in San Antonio. These trips are made special by the composition of the group, and this was a wonderful one. On behalf of Eric and Alex, I want to thank you all for joining us on this Texas adventure. You made it one to remember! Good birding to all.

Surprising to see one at the Frio Bat Cave attempting to hunt bats. This was my first sighting at this location despite many visits over the years.

Surely one of the most attractive of the flycatchers found in the United States.

Quite a few of these heard at Lost Maples with a few seen well.

BELL'S VIREO (Vireo bellii)

Plentiful in scrubbier habitats.

Field Guides Birding Tours
Our final evening was set aside to enjoy the spectacle of free-tailed bats emerging from the Frio Bat Cave. Raptors have learned to take advantage of the resource. Alex caught this dramatic moment a Red-tailed Hawk lurched for a bat.
