An adult Herring Gull (
Larus argentatus) loafs on rocky riprap where the Barnegat River meets the Atlantic Ocean. I made this image on an epic December 13 (2022) trip to Barnegat Light, New Jersey, with a late day spur trip to the
Edwin Forsythe (formerly Brigantine [they never should have changed the name]) National Wildlife Refuge.
While there was plenty of arguably more exotic fare to watch/photograph at Barnegat, this wise old bird caught my eye, and I seldom can resist photographing these beautiful and quite interesting animals. While some (many?) people disparage gulls, these are people that know nothing about them. A book could be written on the Herring Gull and its fascinating behaviors and history. I'll drop just one tidbit now, a facet of these big birds that always makes me ponder old warriors such as the bird in the image.
The oldest known Herring Gull lived to 49 years of age. But as our sample size of Herring Gull longevity is miniscule, and there are estimated to be around 300,000 of them in eastern North America alone, we can be sure that older individuals are out there. Indeed, it's possible that some ancient gulls might have a life span comparable to humans (or large parrots). Clever and adaptable, Herring Gulls have learned lots of interesting tricks, as we shall see.
PHOTOGRAPHY NOTE: I made the above image with the Canon R5, a new iteration of Canon mirrorless cameras that I have increasingly become infatuated with. In fact, my main trial run with the R5 was October 2021, to Barnegat Light and this general area of New Jersey. I have discovered that the R5 is friendly to the Canon 1.4x III extender coupled to my Canon 800mm f/5.6 lens. I've never been able to adequately dial in any other camera body to that combo, in spite of seeking professional "micro-adjustment" services. The Herring Gull image is completely uncropped. It wasn't all that far, but with 1120mm of firepower, it wasn't all that close, either. The 800/1.4x combo does lose a bit of sharpness (the raw 800 is stunningly sharp) and focus issues increase with distance as might be expected, but when working with subjects at a reasonable range, it works well. For much of the wildlife work that I do, more is better when it comes to reach. I'd love to have Canon's new RF1200mm lens, which presumably is perfectly dialed in and definitely much lighter than my tank of an 800, but at $20,000 it isn't in the current budget. Anyway, all of the following images other than the landscape shot were made with the 800mm/1.4x = 1120mm combination.
The wildlife drive through Edwin Forsythe National Wildlife Refuge. That's Atlantic City, New Jersey across the bay. While I made this shot on my October 2021 trip, this is the exact spot where the following action took place.

An adult Herring Gull has just dropped a Blue Mussel (
Mytilus edulis) from several stories up.
NOTE: I think I have the bivalve's identification right. If you know better, please let me know.
I think every time I have been here, there has been Herring Gulls dropping mussels on this section of road. This time, I resolved to obtain some decent imagery, in between shooting big blastoffs of Brant and Snow Geese, along with other interesting fowl.
Another adult Herring Gull watches his freshly launched mussel missile drop to the road far below. I believe the thread-like projections from the mussel are its
byssus - specialized filaments that enable the mussel to firmly affix itself to bed sites. The byssus isn't enough to prevent clever and powerful gulls from ripping the mussels from their moorings, however. I noticed the handful of mussel-hunting gulls would foray into the nearby bay, and then return with a Blue Mussel. It did not seem like it was very hard for them to find the hard-shelled prey. I wondered why ALL the Herring Gulls didn't seem to engage in hunting this target. The meaty innards of a mussel must be exceptionally rich and nutritious fare. Maybe only the smartest Mensa gulls can figure out the steps involved?
It wasn't just seasoned adults that were catching and dropping mussels. This is a first-year Herring Gull (it takes this species four years to attain adult plumage), doing the same.
As I'm sure you realize by now, the gulls drop the hard-shelled bivalves on the roadbed to crack their thick shells. Here's a young gull holding a just-smashed mussel. The clam-cracking bird quickly flutter-drops to the road right behind the victim, as to not quickly claim one's prize would mean piracy by other gulls would likely happen.
An adult gull flies out to the bay with a shattered mussel. They always did this, probably to find a more private spot to dine in and hopefully a hassle-free zone from other gulls. For a Herring Gull, I imagine Blue Mussel is fine dining indeed; probably the equivalent of a meaty steak to a person.
Dropping hard-shelled potential food to crack it open is a very well-known behavior by large gulls. I've seen it on a number of occasions in widely scattered areas. But the wildlife drive at Edwin Forsythe is probably the easiest place that I've seen to actually observe and make photos of the gulls dealing with mussels, at close range.
TIP: This is a VERY popular refuge, and busy days bring lots of cars to the wildlife loop. Far better to visit on a weekday as opposed to weekends, if possible. Too much traffic really horns in on the gulls' efforts to use the road as a mussel-smashing substrate. From my limited experience here, the southernmost section of the wildlife loop (towards the beginning) near the can't miss observation tower is the best place to catch the gulls in action. And the end of day will probably provide the best lighting.
