Tern time

IMG_8469-2

A committee of terns on a dock, Indian River Lagoon, Hutchinson Island side. That’s the bridge between Hutchinson Island and Sewall’s Point in the distance.

IMG_8473-2

The Royal Terns look a lot bigger than the Sandwich Terns, when they are right next to each other.

IMG_8477-2

It was around 8:30 a.m. I wonder if they spent the night “roosting” on this tern-popular dock.

IMG_8482-2

One or two would fly off south now and then.

IMG_8484-2

I think that’s a juvenile Laughing Gull. The Royal Tern looks pretty big next to a gull too.

Gulls and terns (and skimmers) are in the same family, Laridae.

IMG_8486-2

Laridae is a family of seabirds in the order Charadriiformes that includes the gulls, terns and skimmers. It includes around 100 species arranged into 22 genera. They are an adaptable group of mostly aerial birds found worldwide.

IMG_8488-2

Royal Terns and Sandwich Terns in this pic, both in the genus Thalasseus… from the Greek Thalassa, meaning “sea.”

IMG_8489-2

The big Royal Terns are Thalasseus maximus and the smaller Sandwich Terns are Thalasseus sandvicensis.

IMG_8496-2

Thalasseus terns feed by plunge-diving for fish, almost invariably from the sea. They usually dive directly, and not from the “stepped-hover” favoured by, for example, the Arctic tern. The offering of fish by the male to the female is part of the courtship display.

IMG_8497-2

These species have long thin sharp bills, usually a shade of yellow or orange except in the Sandwich tern and Cabot’s tern where the bills are black with yellow tips in most subspecies. All species have a shaggy crest. In winter, the Thalasseus terns’ foreheads become white.

“Sandwich” refers to Sandwich, Kent, England where they were first described and classified by ornithologist John Latham in 1787.

Collective nouns for our fine feathered Thalasseus friends?

As author Chloe Rhodes explains in An Unkindness of Ravens: A Book of Collective Nouns, unlike proverbs, rhymes or homilies, many of these words endure because they were recorded and published in Books of Courtesy handbooks designed to educate the nobility. ‘They were created and perpetuated as a means of marking out the aristocracy from the less well-bred masses,’ she writes.

Bait run plus terns

IMG_7218-2

This was the scene at Bob Graham Beach, Hutchinson Island last Tuesday: a thick black line of bait fish in the blue-green ocean.

IMG_7200-2

A fisherman told me the bait fish running at this time of year are called “anchovies.” The big and famous mullet run comes a few weeks later.

IMG_7201-2

I love when the wind and surf are calm enough to see into the water like this. It’s like the Caribbean then, instead of the often-windy Shipwreck, I mean Treasure Coast.

IMG_7203-2

Tarpon were cruising along right offshore beyond the bait line, occasionally swirling on the surface as they fed on little fish.

IMG_7205-2

I didn’t get any good tarpon shots but trust me it was an impressive show and everyone on the beach was enjoying it.

IMG_7206-2

Bait clouds.

Here’s a drone video of tarpon during the mullet run at a beach further south on the Florida coast: Florida Mullet Run & Tarpon.

IMG_7208-2

But let’s get to the birds!

Ruddy Turnstones still in breeding plumage. Must be migrating down from their northern nesting areas.

It may be 90 degrees but “bird fall” (and fish fall) has begun.

IMG_7209-2

Buddha bird.

Be the bird.

IMG_7227-2

A little further down the beach, lots of terns including this Royal.

I’ve been trying to learn our local terns!

IMG_7229-2

This one is a Sandwich Tern.

A bird of marine coasts of the southeastern United States and the Caribbean, the Sandwich Tern is readily identified by its shaggy crest and yellow-tipped black bill.

IMG_7237-2

The tern with the large orange bill is a Royal Tern. Sandwich Tern above and non-breeding Laughing Gull on the right.

IMG_7239-2

Step aside for the lone White Ibis, little Laughing Gull!

IMG_7240-2

A beach full of fat and happy birds, having recently fed on the abundant bait fish.

The terns do the work and the gulls steal their fish, often. Though I have seen the gulls skim a fish right off the surface of the water too.

IMG_7245-2

Sandwich Tern.

IMG_7246-2

Whee!

IMG_7251-2

I think the one smaller tern with the orange bill is a Common Tern. But they look like Forster’s Terns too.

IMG_7252-2IMG_7254-2

Sandwich Tern and some Laughing Gulls.

IMG_7255-2

Very distinctive bill, in color and length – I think I’ve learned this tern.

Family dynamics of Sandwich Terns?

These women stopped and turned around when they got to the birds. Very polite of them not to make them fly.

So many fish to choose from.

Away they go.

IMG_7311-2

And down the beach I find one little Piping Plover! (I checked on What’s This Bird to make sure it wasn’t a Snowy Plover, since they look alike – online – to me.)

Everyone needs a secret beach hideout. Researchers only recently discovered that more than one-third of the Piping Plover population that breeds along the Atlantic coast spends the winter in the Bahamas.

Don’t you want to be the researchers?… hey, we found the Piping Plovers… in the Bahamas!

Royal tern

tern1

Royal Tern, Thalasseus maximus, over the Indian River Lagoon near the Ernest Lyons Bridge that runs between Sewall’s Point and Hutchinson Island.

The royal tern typically feeds in small secluded bodies of water such as estuaries, mangroves, and lagoons. Also, but less frequently, the royal terns will hunt for fish in open water, typically within about 100 metres (110 yards) off the shore. The royal tern feeds in salt water and on very rare occasions in fresh water.

tern2

The genus name is from Ancient Greek Thalasseus, “fisherman”, from thalassa, “sea”. The specific maximus is Latin for ‘”greatest”.

tern3

This one appeared to be scanning for fish but I did not see it dive.

Their pointy orange bills are distinctive and in breeding season, in late spring, they have a complete black cap with some jaunty feathers sticking up on top.

tern5

From Audubon.org

Common along tropical and subtropical shores, the Royal Tern is a characteristic sight along the Gulf Coast and southern Atlantic Coast, less numerous in California. Aside from a few interior localities in Florida, it is almost never found inland except after hurricanes.

They eat fish and crustaceans like crabs and shrimp.

Forages mostly by hovering over water and plunging to catch prey just below surface. Sometimes flies low, skimming water with bill; occasionally catches flying fish in the air, or dips to water’s surface to pick up floating refuse. May steal food from other birds. Sometimes feeds at night.

The bird with the old man hairdo

Incoming.

Sunday on the dock.

img_4806-2

The black feathers on their heads remind me of an old man’s haircut, particularly my great-grandfather Pop-Pop.

img_4807-2

I like to watch them fish, with their fast aerial dives. But it’s easier to get a picture when they are hanging out on the dock.
