Birding the Galapagos

Almost exactly two years ago, our family was fortunate to visit the Galapagos Islands. Braden and I eagerly anticipated the birds we might see, but weren’t sure what birding might be like in one of the world’s most famous places. Our findings? That while the Galapagos is full of fascinating birds to see, it is one of the world’s best places to think more deeply about birds, their evolution, and behavior.

Upon arriving, the first thing we noticed is how tame Galapagos birds are. Many, after all, evolved with few predators to worry about, and this was clearly demonstrated as we hiked within a few feet of nesting Blue- and Red-footed Boobies, Magnificent Frigatebirds, and a sublime Galapagos Dove. Even Yellow Warblers hopped around our feet seemingly without fear. Just try getting close to one in Montana! This close proximity, of course, was great for photography, but also for watching bird behaviors up-close.

One time, we stood thirty feet from four or five male frigatebirds sitting in stick nests that they had built. When a female flew over, the males all spread their wings, puffed out their gular pouches, and “rattled” their beaks. It was their way of shouting “Choose me!” It worked too! As we watched, a female landed next to one of the males to begin the “dating” rituals.

The most interesting Galapagos birds were the finches. Perhaps the drabbest, least noticeable birds in the islands, the finches played a key role in helping Charles Darwin tease out the basics of evolution by natural selection. How? When he visited the islands in 1835, he collected many animal specimens—including finches—from the different islands. Back in England, a colleague informed him that the finches actually included many different species. This, along with observations he’d made on Galapagos tortoises and other species, helped Darwin realize how different habitats and conditions can shape animals and create new species.

During our visit to the islands, Braden and I barely got started learning to identify the different finches, but we soon began to distinguish between larger and smaller species. Evolution has especially acted on the birds’ beaks, both in size and shape, as the beaks are a key to what size seeds and other foods the birds can eat. Not surprisingly, the beaks have formed the basis of long-term studies by modern scientists, as documented in one of my favorite books, Jonathan Weiner’s excellent The Beak of the Finch: A Story of Evolution in Our Time. Check it out—and if you ever get a chance to visit the Galapagos, jump on it. It will permanently alter your perspective on birds and life on our amazing planet.

Braden and I never had any doubt about our Bird of the Trip. Every day, Blue-footed Boobies delighted us with their incredible flying and fascinating behaviors! (photo by Sneed B. Collard III)

Irruption!

This year, there are more Evening Grosbeaks than ever at our feeder–but still nowhere near the amount we saw our first year of birding. (photo by Braden Collard)

During our first year of serious birding, my dad and I thought Evening Grosbeaks were common. Every day in fall, if you just walked the block from our house to Rattlesnake School, you would be amazed at the numbers of these boisterous finches gathered there. There were hundreds, maybe even a thousand of them in their drab fall plumage, tearing apart any pinecone unlucky enough to be spotted.

Two years later, during our first major Big Year (which you can read about in my dad’s fall book Warblers and Woodpeckers: A Father-Son Big Year of Birding), we saw only two individuals: a pair we briefly glimpsed up Pattee Canyon while staking out an American Three-toed Woodpecker nest.

How is it possible that we saw tons one year and only 2 another year? Irruption.

When I say irruption, I’m not talking about a misspelled version of the thing happening in Hawaii right now. An irruption is a mass migration of birds (in this case) to a different area, generally south. Finches are the main type of group that has irruption cycles, but many birds that winter in the U.S. and southern Canada, such as Snowy Owls, Rough-legged Hawks, Bohemian Waxwings and Northern Shrikes also irrupt. Irruption almost always results in large numbers of birds appearing in areas where they normally aren’t, however it isn’t historically unusual.

One of the main reasons for irruptions is food supply. For example, when there aren’t enough rodents to go around up north in winter, Snowy Owls will generally move south into Northern U.S. states. Sometimes, if the shortage is extreme enough, the northern birds will extend their ranges past their usual limits and end up in places that are unheard of. During a major Snowy Owl irruption year, for instance, Snowies were found as far as Texas and Hawaii.

Irruptions can occur due to food abundances, too. The year before we experienced the Evening Grosbeak overload probably had pairs producing higher amounts of young than usual. The next year, the young had nowhere to go, since all of the territories up north were filled, so they moved south into Missoula.

While not as big of an irruption year as before, this year’s Evening Grosbeaks are costing us plenty in bird seed! (photo by Sneed B. Collard III)

This year and last year haven’t quite met that first year’s standards yet, but it has seen crazy irruptions for tons of finches. Last winter kicked off with large numbers of grosbeaks and Pine Siskins, while this year Common Redpolls, Cassin’s Finches and (yet again) more grosbeaks are stealing the stage. Who knows what will show up next?

 

A Banner Yard-Bird Year

Yesterday, when I returned from walking our dog, Lola, I found a mob of Evening Grosbeaks attacking our bird feeder. In the nearby bushes sat a group of nervous Cassin’s Finches waiting for a break in the action, while in various other parts of the yard, I espied Red-breasted Nuthatches, a Song Sparrow, Black-capped Chickadees, a Pygmy Nuthatch, Violet-Green Swallows, and what I believe to be our First-of-the-Year Calliope Hummingbird. I freely admit that some of these birds would have been here anyway, but in many ways, this delightful assemblage was the culmination of dedicated, determined home habitat improvement.

The last few years, Evening Grosbeaks have been regular visitors to our yard, even if they stay only a few days. (photo by Sneed B. Collard III)

We moved into our just-built house twelve years ago. Our new neighborhood had destroyed an old apple orchard that undoubtedly had provided habitat for a host of animals including birds, so one of my goals was to not only get a lot of plants in fast, but to plant as many native plants as possible. I painstakingly picked out a huge variety of annuals and perennials, imagining the native Eden that would soon blossom here.

The deer had other ideas.

For the next ten years, I waged an annual battle with these ruthless ungulates as I planted native plants and the deer gleefully ripped them out. During that time, their tastes evolved to include both “deer delicacies” and the vast majority of so-called deer-resistant plants various experts had touted. Fortunately, a few of my hardier species survived including buffalo berry, maple sumac, mountain mahogany, and golden current—along with aspen, larch, pine, and other plants that I took pains to protect.

Over the past three or four years, our persistence has visibly paid off as we have observed an ever-greater variety of species and numbers not only feeding from but finding shelter in the habitat we have created.

Of course, the feeder that Braden faithfully refills and the two new bird houses we installed don’t hurt (more on that in a future post), but most rewarding is to just spot birds such as Ruby-crowned Kinglets, Song Sparrows, and Lazuli Buntings that find safe haven in the plants that we have nurtured.

As our vegetation cover has increased, Ruby-crowned Kinglets have become regular visitors in both fall and spring. (photo by Sneed B. Collard III)

The take home message? Creating great bird habitat takes effort and persistence, but it’s absolutely worth it. In an age when birds face an overwhelming barrage of threats from habitat destruction to global warming, it’s the best feeling to know that we are making a few birds’ lives just a little bit better.

Big Hole, Big Day, Part Two

(continued from Big Hole, Big Day, Part One)

On the way to Dillon we stopped to admire First-of-Year Swainson’s Hawks and Western Kingbirds, many more Bald Eagles and one more Golden. Then, after a quick lunch at Sparky’s Garage, we cruised Central Street, Blue Jays in mind. A yard here received a pair daily, according to eBird, but we struck out. However, at the end of the street we were about to turn around when a black bird with a tail like a boat rudder flew across the road. Common Grackle! We followed it and soon found its buddies hanging out at a feeder. These birds are harder to find in western Montana than most places, so seeing them was a treat.

Surprisingly, the feeder and others nearby also were covered in finches—Cassin’s Finches! We had been seeing them at our feeder recently as well, and these sightings pretty much confirmed it was an irruption year for them.

Finally reaching the Big Hole, we began our exploration of the Bannack area by driving four or five miles down Bannack Bench Road, which supposedly harbored Greater Sage-Grouse, Gray Flycatchers, Sagebrush Sparrows and Sage Thrashers, the latter three all Great Basin specialties. The birds shunned us, but where the road met the main road into the State Park, we picked up Mountain Bluebirds, a pair of Barn Swallows, and two Cinnamon Teal floating down Grasshopper Creek.

Hiking around the ghost town itself triggered a flood of memories and even more bird species. Rock and House Wrens sang from the hillsides, Red-naped Sapsuckers drummed on cottonwoods, and a surprisingly large flock of Clark’s Nutcrackers called from the scrub.

As the afternoon lengthened, we decided to give Bannack Bench Road one more try and were rewarded by a single Sage Thrasher, a Lifer for us. As the road emptied out into farmland, we also encountered a snipe singing on a fence, the coolest experience we’d ever had with one! Approaching and passing Clark Canyon Reservoir, we added White Pelican, Sandhill Crane, Northern Shoveler, Common Loon and Prairie Falcon to our day lists before tiredly making our way to Butte for the night.

The next morning, we rounded out our weekend with a visit to Warm Springs before heading home. There, we saw an impressive variety of ducks and grebes, including an insane number of Cinnamon Teal. Taking a final drive out to the Ducks Unlimited Ponds, we suddenly heard a loud, alien call. My dad looked at me and said, “Sora?” We leaped from the car and within minutes, spotted a small, chicken-like bird scrambling through some cattails while two other Soras called nearby. It was a Montana Lifer for us, and an awesome way to end a memorable “Global Big Weekend.”

Big Hole, Big Day–Part One

Braden here again.

May 5th was designated as the annual Global Big Day this year by Cornell University, the leading university in ornithology. Birders around the world were supposed to go out on that date and see, hear and record as many birds as possible on one day, on the site called eBird run by Cornell. Early May is the perfect time for a Global Big Day—migration is in full force: spring in the northern hemisphere and fall in the southern hemisphere. That means birders can go out and record upwards of 150, 200 species.

Migrants, however, weren’t on our minds when my dad and I set out the morning of May 5th; we were looking for species that had already arrived and set up territories. We were headed to the Big Hole, a big, dry valley in southwestern Montana. We hoped to hit some locations for various year and life birds, then finish up at Bannack State Park, an old ghost town that my dad had written a novel about years before. We were also indecisive about spending the night in Dillon or Butte and hitting Warm Springs Waterfowl Management Area, an old favorite of ours, the next morning.

We first stopped at my Eagle Scout project site at Rock Creek to check on the plants I’d planted to help restore bird habitat there. The majority of plants looked healthy, and the soil was moist, delaying having to water them for at least another week. Hooray! The bird life around the property chirped with activity. Vesper Sparrows sang from the fence, an Osprey guarded its nest from intruders that might want eggs for breakfast, and Cliff and Tree Swallows circled above. Right as we were pulling out, we were surprised by a very cooperative Red-naped Sapsucker drumming on a snag right in front of us.

The drive down was very birdy, and we got to our first stop north of Dillon at about nine in the morning. It was a road leading off into shortgrass prairie, and our goal here was an almost Montana-exclusive bird: the McCown’s Longspur. We had seen Chesnut-collared Longspurs last summer in eastern Montana, but now hoped to pick up their less common relatives.

As we began driving down the road, we quickly began seeing more common prairie birds—Horned Larks, and Savannah and Vesper Sparrows. Soon, though, I spotted a bird fly into the air and then coast to the ground singing, similar to the display of the Chesnut-collareds we’d seen last year. As it landed, I got my binoculars on it. The bird was gray, with red wings, a white face and a black chest—McCown’s!

We continued down the road and then turned onto I-91, a highway parallel to I-15. As we said farewell to the longspurs, I turned my attention to raptors on power poles. Almost immediately we came across a huge one.

“Is it a Golden?” I asked, straining my eyes.

As we approached, its white head became obvious. Bald Eagles are still cool, but much less rare in Montana. Surprisingly, they’re also larger than Goldens.

The second raptor, however, appeared to be just as large with no white head. As we passed, I glimpsed its face—the golden hood and powerful eyes of a Golden Eagle.

“Golden!” I said. “Turn around, turn around!”

We pulled into a parking lot across the road and and watched it, then tried for photos. It was fairly skittish, though, and flew away before we got close. We then continued driving, heading for our next stop: Dillon.

To be continued.
