Flying Rats. Parking Lot Bird. Beach Pigeons. A Health Hazard. A Nuissance.

There are many epithets given to the unpopular group of birds collectively known as “seagulls”. These birds are often overlooked, even by birders. 

Gulls are found in most coastal urban areas including parking lots, school yards or perched on the roof of fast food chains, often chasing other birds and sometimes even small children. While the rising human population harms many species of animals, gulls seem to prosper with our desrtruction and altering of the earth’s landscapes.

From a birder’s perspective, gulls all seem to look alike and can be devilishly difficult to identify. Some first year birds look like a Dickensian chimney sweep, covered from head to tail in dark-gray soot. Or you have adult birds that all seem to have the same proportion of white and grey. It’s easy to understand why many birders ignore them altogether. With gulls, the devil is truly in the details.

So it was that on a Sunday morning that Dickissel and I came to be on a bluff above Pilarcitos Creek to observe details.

From our perspective, the creek was directly below us and beyond the water was Venice Beach and further down slope was Half Moon Bay. Directly in front of us were gulls bathing and preening in Pilarcitos Creek while up on the beach there where other gulls that were preening or resting on the sands. In total, the mixed gull flock included about 150 individuals.

This flock  was truly mixed. It included common gulls at different plumages on their three to fourth year journey to adulthood. And none of them resembled each other, hence the importance of observing details (and a scope helps).

The first gulls that stood out were the five adult and one juvenile black-legged kittiwakes, enthusiastically bathing in the creek. 2017 has been a fantastic year for this normally scarce species on the coast. For whatever reason, this winter, these petite pelagic gulls were abundant on beaches and off shore rocks. The kittiwakes kept their distance from the larger gulls in the communal bath that is Pilarcitos Creek.

One juvenile kittiwake would vigorously preen and bath at the base of the main flock and slowly float downstream just below our perch where we could observe it’s bold “M” stretched across it’s wing span and it’s black rimmed tail. Dickcissel christened the young one our “Homie”.

Aside from the kittiwakes, the most common gull present were westerns, followed by California, mew, ring-billed, and two glaucous-winged gulls. But we were searching for a large white Artic gem. This would be the largest and whitest gull around, a gull that cohabitants with polar bears and its foragaging portfolio includes predation, this gull was the glaucous gull (Larus  hyerboreus).

A large white gull with a pied bill of black and bubblegum pink appeared amoung the gulls washing in the creek. This gull really stood out. It washed and preened for a good 15 minutes allowing close study thought the scope. After it’s bath, the glaucous flew up to the beach to continue to preen.

What I noticed about the glaucous is that all the western gulls surrounding on the beach, it gave it a wide berth as if they knew the glaucous was different. Bigger, more aggressive, and menacing. All the other gulls stayed outside of pecking distance.

Some beach walkers flushed the gull flock, they took to the air, circled around and eventually returned to the creek and beach. I scanned the flock and refound the glaucous. I then noticed a bird at the upper edge of the flock that stood out. It stood out for a few reasons: first is was standing apart from the flock, as if it didn’t belong, second it’s bill shape was very different from the others, and lastly it’s dark eyes was framed in a broken white circle. This was a rare west coaster, a laughing gull (Leucophaeus artricilla).
