It’s true that some anis do spend the winter here some winters but you aren’t likely to see an ani in the RGV before May of each year. We saw our FOY (first-of-year) anis today at Estero Llano Grande State Park. A pair of birds were found in the “tropical area” of the park at about 2 in the afternoon. They were working their way through the understory of the area and dropping down to the ground among the tall grasses to search for insects.

Estero Llano Grande is among the best places to look for anis every year. Check eBird for other reliable locations.

After months of severe drought, wetter conditions have prevailed in the RGV for the past month. With each passing cool front rain has occurred and waves of migrants have dropped in to spend some time refueling for their migration north. In one case, while we were away in New Mexico, there was a major fallout event and even now many migrants can be found throughout the valley.

Yesterday, we counted 86 species of birds at Estero Llano Grande State Park and this morning we saw almost 50 in the postage-stamp-sized habitats of the Valley Nature Center (VNC). Included among these totals were dozens of warblers, vireos, flycatchers, and other neotropical migrants.

Local breeding birds are also taking advantage of the spring rains to build nests and raise families. We saw two juvenal-plumaged Clay-colored Thrushes at the VNC and several young Plain Chachalacas were following their parents through the brush there as well.

In just a few days the migrants will have moved on but we’re looking forward to following the local birds as they continue their breeding season, including a pair of Clay-colored Thrushes that have taken up residence in our own back yard.

The trip was mostly about building a small cabin that will be used to house our solar electric system and support the solar panels, but we did manage to do some birding in New Mexico and Arizona while we were there. Spring migration was in full swing and there was a diverse mix of winter holdovers, returning summer residents, and migrants. Some of the highlights included male Lark Buntings that had completed the spring molt into their striking black-and-white plumage, a simply stunning pair of Elegant Trogons that allowed us extended views from no more than 20 yards away, and a colorful assortment of fully decked out warblers, tanagers, and orioles.

The star of the show, however, was a very cooperative and easily found Crescent-chested Warbler that made an appearance in Cave Creek early in our stay and spent over two weeks delighting birders from far and wide. For those of you who might not know, this is an incredibly rare bird for the U.S. There have only been a handful of confirmed records, mostly in Arizona and a few in Texas, over the years.

Our pictures are not great but we did document our first new species since the conclusion of our Big Year. Michael had seen this species many times in Mexico but this was our first sighting in the U.S.

It wasn’t quite as magical as last week. The diversity of birds was about the same but the overall numbers were somewhat lower. It was another mini-fallout and even more mini than a week ago.

Still, there were plenty of highlights to please the eyes. Many of the birds, in their fresh spring plumage, seemed to be glowing. Some of our favorites were the Indigo Bunting, Summer Tanager, and Ruby-throated Hummingbird.

As always happens during migration season the mix of species was noticeably different after the passage of just a week. (That’s what makes spring on the island so interesting!) For example, we didn’t see any Hooded Warblers and the Swainson’s Warbler had moved on. This male Blackpoll Warbler was among the new arrivals.

There was a decidedly western tinge to the mix this time. Dozens of Western Kingbirds were hawking insects all across the island and nearly every good-sized bit of habitat had a Bullock’s Oriole.

Sadly, we noticed that the good-sized bits of habitat are still shrinking on South Padre Island. Despite the large crowd of birders and their obvious benefit to the local economy, the city still hasn’t made much of a commitment to preserving green space to continue to attract the birds and birders. When Michael was director of the Rio Grande Valley Bird Observatory at the Valley Nature Center, those groups helped the Valley Land Fund protect the woodlots on Sheepshead Street. Soon after, Wil and Gill Carter planted the warbler rest at the Convention Centre. These were private initiatives on both private and public land and the city seemed to “get it.” But over a decade later not much more has been done and the development of the island continues to shrink habitat.

We’ll continue to report on our birding adventures as the season progresses, wherever we might be. In the meantime, happy birding!

A cool front had passed through the day before and the winds had switched from our prevailing southeasterly direction to the north and northeast. This put the winds squarely in the face of the early season migrants and they were obliged to drop in and pay us a visit, resting and refueling in the limited habitats of the village of South Padre Island. We estimate that there were about 20 species of warblers on the island, based on the 16 species we saw and reports by other birders. One of the favorites was this Kentucky Warbler at the Convention Centre. Other small passerines included vireos, sparrows, flycatchers and orioles. Especially prominent were dozens of Orchard Orioles feeding on bottle brush bushes planted at the “warbler rest stop.” Not to be outdone by the passerines, shorebirds and Franklin’s Gulls swarmed in the wetlands. We can’t remember when we’ve seen more Franklin’s Gulls! Another favorite was the Pectoral Sandpiper who spent hours feeding on the lawn near the parking lot at the Convention Centre. There were some late winter hold-overs on our list as well. A Common Loon was seen feeding in the Laguna Madre and an Osprey was found eating its catch on a snag. The most interesting “winter bird” was the Carpodacus finch at the Convention Centre. There was a hot debate about whether this was a Purple Finch or a Cassin’s Finch. At first, Michael was leaning toward Purple. Then we started to think Cassin’s. Finally, we decided to call it a Purple Finch. We’re not sure how it ended up on other birders’ lists. In either case, it’s a very rare visitor to deep south Texas. Even more of a mystery was the weirdly colored Spizella sparrow that graced the lawn for a brief visit. It was hanging out with Clay-colored Sparrows and looked like one … except for the extensive orange and yellow coloring of its head and breast. The general feeling is that it is a Clay-colored with extra yellow and orange pigments in its feathers. It sure caused a stir though!

All-in-all it was a great day to kick off the spring migration in south Texas!

We answered our own question for a few of those species: State Forest State Park in Colorado for American Three-toed Woodpecker, Sandia Crest in New Mexico for rosy finches, Great Salt Lake State Park in Utah for Chukar, and Mercey Hot Springs in California for Long-eared Owl. But we’d like to hear from you about your best locations for some of the tougher species to find.

Send us your top hot spots for your hard-to-find species. You decide what species you find hard-to-find and then tell us where you would suggest we go to look for them.

We’ll visit your spots and see if they are truly slam dunk spots!

Most of the Valley specialties are year-round residents. When spring rolls around they are joined by dozens of species that are just passing through on their way back north. The peak time for this migration is the last two weeks of April but the vanguard of migrants starts to arrive by mid-March and the stragglers are still passing through in mid- to late- May. This two-month migration window provides some of the best birding of any place and time on the entire North American continent.

If you only have money to visit the RGV once during the year make sure it’s during the spring migration!

We were seeing many new birds each day at the beginning, but at the end we often went days or weeks without seeing anything new. So, one important tip to seeing more species on fewer dollars is to plan your trips where and when there is the best opportunity to see many new species. That sounds obvious, but it’s not as easy as it sounds.

Even now we are analyzing our life lists to see what birds we still need and then trying to figure out where and when we could see the greatest numbers. For us, we know that we need to take pelagic trips from northern California or Oregon and from the east coast. We also need to take some trips to Alaska. Even though these trips will be expensive, they will provide us with the greatest opportunity to see the most birds for the least cost. Other than that, most trips would only give us the opportunity to see one new species in an area, such as the Colima Warbler in Big Bend National Park or the Himalayan Snowcock in the Ruby Mountains of Nevada. (The cost per species for those trips would be very high. That’s why people who try for record numbers on their Big Years spend so much!)

There are many resources online to determine when and where to see specific birds. Checklists from natural areas can be located at the US Geologic Survey site: http://www.npwrc.usgs.gov/resource/birds/chekbird/.  Just click on the state that you are interested in visiting. A list of checklists will come up and you can click on them and even print them out to take into the field. These checklists include information on the probability of seeing a species as well as the time of year when it is most prevalent. The lists allow you to see many species at a glance but, unfortunately, many of them are old and not completely accurate.

More recent sightings can be located at the American Birding Association’s website http://birding.aba.org/. You can click on the location you are planning to visit to see what has been seen recently in that area. There are also archived lists to see what was seen at a particular time in previous years in that region.

Perhaps the most comprehensive resource is ebird, but only one species can be entered at a time. Go to http://ebird.org and click on the explore data tab. Then click on the range and point maps. Finally, enter the species you would like to see. You may also want to limit the search to the last three years so that you get recent data. The dark purple indicates the best areas to see a particular species. Then enlarge the map. When you see the “bubbles” click on them to see the location and date(s) of the sightings. This gives you not only an idea about where to see specific birds but also the time of year when they are most often seen. In addition, next to many of the sightings is a link to the complete checklist from the person reporting, which indicates what other birds were seen at the same time as your target bird.

As many people noted during our Big Year, we returned to the same areas multiple times.  No matter what time of year you visit a birding hotspot, you are going to miss some birds. For example, people visit South Texas in the winter so they can see the Whooping Cranes as well as many other South Texas specialties. But some birds don’t return until after the Whooping Cranes have headed north. For example, the Groove-billed Ani is unusual to see in South Texas until April or May so you are unlikely to see both cranes and anis on one trip. But multiple trips obviously cost more than a single trip to a region, all the more reason to plan carefully (and to hope for good luck!).

There is no way to avoid the law of diminishing returns but online resources will make your birding more cost efficient.

Our approach to the year was to travel extensively to visit all the main habitats of the continent in multiple seasons. All of the travel, except for pelagic bird trips, was done by car. So, the single most important cost consideration for us was the cost per mile of our vehicles. We’ve said it before, we would have had to stop about June (with “only” 600 species or so) if we did not use our Prius for 3/4 of the miles we traveled.

The combined mileage for our Prius and our minivan was about 40 mpg. Since we drove nearly 60,000 miles in the year, that works out to about 1500 gallons of gasoline. A typical economy car gets a combined mpg of about 30. So, we saved 500 gallons compared to that. A typical van or SUV gets 25 mpg or less, so we saved even more compared to that.

Our average cost for gasoline was about $3.50 per gallon. Based on that, you can see that over half of our total budget was spent on fuel ($5,250 out of $10,376). Had we used a typical car that amount would have been $7000 or more. We would have had scant resources left for all of our other expenses.

So, the “secret” to our Big Year was to drive a fuel efficient car.

The numbers of most small birds are noticeably lower than in previous winters. Whereas we often saw dozens of Orange-crowned Warblers, for example, we now see just one or two on a typical walk in their habitat. That seems to be the case for most other insect-eating birds as well. Without rain there is scant plant growth for the insects to eat and fewer birds up the food chain.

Resident seed-eating birds have fared even worse. Populations of Northern Bobwhite have crashed, and we didn’t even see a single grassland sparrow during our recent birdathon day. Soils are bone dry and there is no indication that any new plant growth is imminent as the spring season begins.

Water birds are also hard hit. Many ponds and marshes have dried up and it is only where state and federal agencies have been able to buy some water rights to flood parks and refuges that our usual wintering populations of ducks, shorebirds, and waders are hanging on. Water is such a magnet for these birds in these few locations that the birding can be wonderful there … and almost nonexistent elsewhere.

Temperatures have been on the warm side this winter, a further factor intensifying the drought conditions, and strong winds have been frequent, drying out the land even further. It is a perfect storm of dry, dry, dry.

In less than a month the spring migration will be starting and thousands upon thousands of birds will stop by on their way north. Let’s hope there is something for them to eat when they get here.
