Heermann’s Gull fledglings and their watchful parents at their rooftop colony in downtown Seaside. Some of the juveniles with their unmistakable light brown feather edging are fully flighted and hanging out on the sidewalks below. We always worry about their safety but they were staying out of traffic while we saw them, and pedestrians were giving them a wide berth. Like their Isla Rasa cousins these young birds and their parents will soon depart their colony for their migration - even if their “migration” is half a mile to Seaside State Beach!

The Seaside Heermann’s Gulls doting on their new brood of fuzzy, speckled chicks on their rooftop colony, once again living in harmony near their California Gull neighbors. We wish these well-fed little babies the very best as they quickly grow into awkward brown fledglings!

Western Gulls may be an unholy terror for our colony drone surveys during the late nesting season, but we have a soft spot in our hearts for these feisty large gulls. One WEGU pair holds a special place in our hearts, the pair living atop San Francisco Ferry Building Gate B. For over 12 years they have needed no help raising chicks on their little rooftop, but yesterday they did. Because they nest much later than the Seaside Heermann’s Gulls, their 3 chicks are still downy and devoid of flight feathers. One of them had fallen down to the platform below, wandering about near the ferry ramp while hundreds of ferry passengers walked past it, some of them photographing this adorable but helpless big baby. A sibling on the roof above flapped its stubby wings and hopped in the breeze, demonstrating how this chick must have fallen. After consulting with we determined it wasn’t safe there with all the pedestrian and vehicle traffic and land predators, so I got my rescue kit (i.e., rode the BART train back to the East Bay and then drove back to the Ferry Building) and caught the chick in a cat carrier. Of course, it alarm called and immediately both parents and about a half dozen other angry Western Gull adults hovered ominously around me while I loaded it in. Somehow they didn’t attack or even crap on me as I apologized to them and whisked the chick off for a 1.5 hour road trip to IBR. The chick, who was plump and healthy, will now finish growing up at IBR with other Western Gull chicks already in care before being released. Once I got home and saw my own human chicks I felt rather awful for the gull parents. As far as I can tell they have never lost a chick in 12 years, and I wished there was a way to reassure them that this chick would grow up safely while they raised the other two. But at the end of the day it was the right thing to do, and we are so very grateful that IBR exists to provide a safe place for this chick to grow up. Please consider supporting them and all of their vital rehabilitation work.

Raising (human) chicks of our own caused over a month to pass between visits to Seaside, but the Heermann's Gulls and their California Gull neighbors have thrived in the meantime. The Heermann's Gulls had downy little newly hatched chicks on our last visit, and a month later those chicks are large, brown, and nearly fledged. In taking their first experimental flights a few of them have glided down from the rooftops. This quartet of chicks appears to be from two different families, but have formed a creche watched over by two protective parents, while the other two parents stood guard above on the roof ledge. While we do worry about their safety being near an active alleyway, they do seem to be wary of traffic, and have an unoccupied parking lot for refuge. In a week or two they will be fully flighted, and they, their parents, and dozens more Heermann's Gulls on the rooftop will undertake their "migration" of less than a mile to Seaside State Beach.

A portrait of domestic life for the most conspicuous pair of Heermann's Gulls in Seaside, who chose to build their nest on a narrow ledge on a street corner. While the rest of the colony stays relatively out of sight on rooftops, it's hard to miss this pair in downtown Seaside. While it makes for some lovely photos, we also worry that their conspicuous location could make them targets for unlawful harassment between now and when their chicks fledge in July. You can help us protect this pair and the rest of the colony by letting us know about any harassment you see, and also by reporting any harassment you see to federal or California Fish & Wildlife departments online, or at the following numbers.

Happy Mother's Day from the Seaside Heermann's Gulls! Being a gull mom is never easy, between finding and defending a nest site, brooding, and protecting and raising 2 or 3 chicks, but fortunately gull dads are equal partners in these travails of biparental care. This female is resting but also remaining on guard duty while her mate takes a turn brooding eggs on the nest.
