Bird Tracks Are a Real Thing

Birding is primarily a visual activity. We go out to see birds. Our study aids are guidebooks dominated by pictures and written descriptions of birds’ appearance and behaviors. We bring binoculars and scopes with us to help us see the birds. As you get more field hours in, you will increasingly rely on sound to detect and identify birds. Still, birders will often stare at a bush or tree long after confidently identify the bird hiding inside by its call. That’s because they prefer to see the bird. Indeed, many birders will only reluctantly, if at all, list a “heard only” bird on their lists. For whatever reason, seeing is believing.

Still, one visual aspect of birding that gets little focus is bird tracks. If you pay attention, they’re actually quite abundant (though only moderately scrutable). But I can recall only two times when anyone I was around remarked about visible bird tracks. Both involved non-birders who noticed them. This neglect of bird footprints is in stark contrast to mammals. There are dozens of field guides that help you identify animal tracks. There are even guides to the tracks of animals (like snakes) that don’t have any feet. While birds are most definitely animals, and they have feet, these books typically don’t include a section on bird tracks. 

But birds leave tracks. They leave them in the sand, and in the snow. They leave ephemeral tracks after walking through a puddle. Spying for bird tracks is a form of birding that doesn’t involve seeing the bird. This post collects a few of the bird tracks I’ve seen in different places.

One good place to find them is at the beach.  I’ve got a bunch of photos of bird tracks from the beach. One of my favorite is the one below. They are Sanderling tracks. I know because I watched the birds running around and then took the picture. I’m not so sure I could ID bird tracks on the beach if the birds that made them weren’t around. Just about every bird track is three toes facing forward, and maybe one facing back (but see this mythical freak). My question about these Sanderling tracks is this — are these the tracks of two Sanderlings moving quickly side by side, or one Sanderling hopping along? If you’ve ever seen Sanderlings work the surf, you’ll probably guess the first. They run, in and out with the surf. I’m not sure I’ve ever seem hop around like a robin might. I found the tracks on the right in the frozen crust of a flood basin in Lancaster, California. They were huge, so I’m guessing a Great Blue Heron made them. 

Despite their delicate lightness, birds also leave prints is in the snow. I don’t get to be around snow all that often. But when I am, I’m on the lookout for bird tracks. During our winter trip to New Mexico, we got a good day of snow. Before it melted, I found all kinds of remnants of birds. Above are the backwards arrows left by Wild Turkeys. Below, a record of a lazy-toed raven crossing the street. Under that is one of my favorite snow prints – a Dark-eyed Junco that left a belly dent along with its feet impressions.

Bird tracks aren’t just found on land. If you’re quick about it, you can see them on water. Coots and cormorants and grebes and geese and other birds taking flight from the water often take a long series of steps on the surface before they get enough lift to fly. Bird tracks in water are about the only ones that you’re likely to find a bird at the end of. All those tracks in the sand and snow are memories of birds long, or impossible, separated from their former path.

Perhaps the coolest set of animal tracks I’ve ever found are not bird tracks. These Triassic Era track fossils are in Capitol Reef National Park. The animal that left these marks was not a bird, or even a pre-bird. Rather, it was apparently an alligator-like creature. It made these impressions over 200 million years ago with its claws on the sandy bottom of a body of water. They were filled in with sediment and then fossilized. Sadly, someone stole some of these fossilized tracks from the national park a few years ago.

So there you have it – a wide-ranging tour of the largely ignored world of bird tracks.

Birding Ballona Creek #1: Jetties and Breakwater

Ballona Creek: Jetties and Breakwater

This post in my guide to birding Ballona Creek covers the area of Ballona Creek where it spills into the Pacific Ocean (that is, the portion west of the Pacific Avenue bridge). The creek channel here is straight as an arrow, thanks to a 1930s channelization project. It is lined by big rock jetties on each side. For convenience, I’ve numbered the unnamed jetties in the map above. Folks sometimes refer to #2 as the middle or long jetty, and #3 as the short jetty (or the southern jetty). They’re the jetties most birders explore, since they’re easy to access from parking at or around Del Rey Lagoon. Jetty #2 and Jetty #3 have flat sidewalk surfaces you can stroll down, though the last 100 yards of #2 is uneven rock. There are far fewer reports from the northern-most jetty (#1). I rarely visit jetty #1 because the bike path doesn’t go past it, and it’s more than twice as far to drive to that side of the creek from my house as it is to drive to Del Rey Lagoon. The bike path is in red, and continues for miles south along the coast.

This section of the creek has a dedicated eBird hotspot: Ballona Creek–Creek mouth, jetties, and breakwater. A hotspot for the Pacific Avenue bridge and another for the general “Playa del Rey/Ballona area” confound things a bit. I’ve never entered a checklist for either of those two spots. If you’re on the jetties, I suggest you use the creek mouth/jetty/breakwater hotspot. 

This is one of my favorite places to visit in my entire 5-mile radius. For starters, it’s got great birds. All year long (except maybe the doldrums of June), the jetties and breakwater offer excellent birding and the potential for rarities. In addition to great birds, I’ve seen green sea turtles and sea lions and whales from the jetties (a gray whale was swimming 10 feet off jetty #3 one day!). And there’s always multiple kinds of watercraft about–from fishing boats and pleasure yachts to jet skis and college rowing crews. The jetties have their share of regular fishermen, and get more casual foot traffic on the weekends. The fisherman don’t seem to bother the birds all that much, but too many strollers tends to scare the birds off.

Another advantage of the jetties is that this isn’t a birding spot that requires getting up at the crack of dawn to see the birds. The tide plays more of a role for seeing birds here than the time of day (that, and how many people are about). If you’re all alone on the jetties at dawn at a high tide, there will be fewer birds on the rocks than if you come mid-day when the tide is falling. That said, there are usually more people around after 10am, especially on weekends.

While I can’t discern anything special about the rocks on one side of a particular jetty or the other, in my experience, the jetty birds prefer the rocks along the creek (that is, the north side of jetty #3 and south side of jetty #2). Between the two, the longer middle jetty gets more birds, and most of them are on the west end of the jetty, after the flat walking surface ends. The sunlight (such as it as) is better in the mornings, when it’ll be at your back (but it’s usually obscured by the marine layer). Visibility in the afternoon, especially during the summer months, is tough with the setting sun behind the breakwater.

On the Rocks

Generally, the further out you get on the jetties, especially jetty #2, the more birds you’ll see. There are a good number of usual jetty suspects feeding on the rocks: Willets, Turnstones (Ruddy and Black), Surfbirds, Sandpipers (Least are more numerous than Western), and Sanderlings are all present year-round, except for a vanishing act they play during June. Black Oystercatchers are resident in small numbers all year, either on jetty #2 or the breakwater. Wandering Tattlers are uncommon but possible any month, except for late April and early May when migrants move through, and June, when they vanish like the others. A small number of Belding’s Savannah Sparrow, an endangered subspecies of Savannah Sparrow that breeds in salt marsh, can occasionally be spotted (almost always alone, and on jetty #2). From time to time, a Black Phoebe will hang out on the jetties. American Oystercatchers get reported, though I’m convinced most of them are Black xAmerican hybrid birds. Despite all the good rocks, only rarely does someone report a Rock Wren. And it’s been almost a decade since a Burrowing Owl spent a couple of weeks on jetty #2.

The approximately 2,000 foot wide breakwater is close enough to the jetties to ID birds with binoculars. It’s often dominated by cormorants. The majority are Brandt’s Cormorants, with some Double-crested and Pelagic mixed in. If there isn’t a feeding frenzy going on nearby,  you might see up to 5,000 cormorants standing on the breakwater. If the wind is blowing the surf onto the breakwater, the cormorants move en masse onto the jetties, and a slow approach will allow for some excellent close-ups. Brown pelicans, gulls, pigeons, and Snowy Egret make up the rest of the birds you’re likely to spot on the breakwater. With patience and luck, you can sometimes pick some rarities out on the breakwater. In September 2013, Blue-footed Boobies showed up. As many a 9 were reported, and the last one stayed until December. In February 2020, a Masked Booby made the breakwater home for 2 weeks. A Common Murre was seen out there during the 2016 L.A. CBC.

In the Air

Despite all the action on the rocks, you’ve got to keep your eyes on the skies, too, as there’s usually plenty of action. Gulls are most numerous, and mob the fishing boats as they return to harbor. Western Gulls are present in the biggest numbers, all year round. The beautiful Heerman’s Gulls (both white-headed adults and chocolate juveniles) are here nearly year-round, but in sporadic numbers. Ring-billed Gulls dwindle in the summer, but are common in the winter. Bonaparte’s Gulls, Short-billed Gulls, Herring Gulls, Iceland Gull, and Glaucous-winged Gulls are strictly winter birds. Only two reports (1975 and 2009) of Glaucous Gull suggest they don’t prefer the area. There aren’t any reports yet of Lesser Black-backed Gull here, but their rising numbers in L.A. County suggest that one will soon be found here. Careful observers can knock themselves out trying to ID the hybrid gulls as well.

The screeching of terns is constant background noise around the jetties. Look for Royal Tern in the winter, Elegant, Caspian, and Least Tern in the summer, and Forster’s by happenstance anytime (another species I think is overreported). Standing on the end of jetty #2 and looking out past the breakwater, you’ll sometimes see Parasitic Jaegers chasing after terns. Osprey like to perch on the breakwater towers, and Peregrine Falcons occasionally make runs along the creek in winter. Belted Kingfisher sometimes move from the lagoon to the bridge, but rarely venture out to the jetties.

On the Water 

There are plenty of birds on the water, as well. Moving about between the jetties and the breakwater you can see a bunch of stuff. Loons can be found from November to May (Pacific, Common, and Red-throated, with Pacific being the least common in my experience). Eared Grebe’s typically outnumber Horned Grebes, and Western Grebes far outnumber Clark’s. Pied-billed Grebes tend to stay upstream of the bridge. A Red-necked Grebe is possible inside the breakwater, but quite rare. Surf Scoters often mass along Dockweiler Beach, and small groups can be found feeding between the breakwater and the jetties. Bufflehead in winter are the most numerous duck, with Lesser Scaup and Red-breasted Merganser common in smaller numbers, and Long-tailed Ducks a winter rarity. The rest of the ducks tend to stay in the lagoon or up the creek.

Over the years, this has been the spot of a few rarity sightings for me. A one-day wonder Red-necked Grebe flew past me in December 2020. A couple of Yellow-crowned Night Herons took up residence on the breakwater in Fall 2021, and there’s a couple more back again right now at the lagoon north of jetty #1. A Vesper Sparrow was on jetty #2 the same glorious September day in 2017 that I spotted a Bar-tailed Godwit further up the creek. Every four years, an Ancient Murrelet or three will show up, the last time in 2018. A Black-legged Kittiwake was on the beach next to jetty #3 one day. In Winter 2014/15, as many as 8 Ancient Murrelets showed up in Santa Monica Bay and several wandered their way into the creek and the marina. Another Ancient Murrelet was spotted at the jetties in February 2018 for a few days.

Whenever you come here–morning, midday, or afternoon; winter, summer, spring, or fall (with the exception of June, when it’s pretty quiet); jetty #1, 2, or 3–you should be able to rack up a pretty good list of West Coast birds.
