Jay walking

DSC_5647

Florida Scrub-jays cooperated with our plan to watch them this morning on a guided Scrub Jay Walk at Jonathan Dickinson State Park.

Mostly cloudy conditions, and the birds came out nice and BLUE in my photos.

When they are banded, Scrub-jays usually get four bands, said Jim Howe, a state park volunteer who leads these walks a couple times a month (except for the hottest months of the year).

But they do sometimes figure out how to remove some of the bands, being the smart little corvids they are.

These Scrub-jays are a federally-designated threatened species. They live only in Florida, have specific habitat needs, and their habitats are shrinking.

They live in the “scrub,” a high-and-dry type of landscape on sandy soil which is desirable for building in this populous state, especially compared to much of low-and-wet Florida.

They are curious and not very afraid of people. We watched five or six in this one area, quite close, hopping on the ground, perched as lookouts in trees, or flying from shrub to shrub.

They gather acorns from the several varieties of low-growing oaks in the scrub. They cache them to eat in winter when there are fewer insects, said our guide.

Hide now and seek later.

There.

A group project, I guess.

I can’t tell if this bird has three or four bands.

DSC_5672

Plenty of dead trees around in this landscape that is regularly burned to maintain it as scrub.

The Red-bellied Woodpecker is a common bird here at Jonathan Dickinson.

Berries on the saw palmetto are favored by raccoons, said Jim.

We walked out on this old Army road, leftover from the time Camp Murphy and its top-secret signal corps was based here in World War II. (That’s my husband John in one of his favorite geek t-shirts.)

A short, slow, flat walk… birding doesn’t get much easier.

DSC_5689

At first I thought this was a small bird of prey.

DSC_5693

I moved to the left and saw it was that small but fierce predatory songbird, the Loggerhead Shrike, that kills its prey with hooked beak, or impales it on thorns or even barbed wire for later eating.

DSC_5697

Also known as the butcherbird. Also not too concerned with the small band of birdwatchers.

DSC_5703

The park has lots of “love vine” in some areas.

Cassytha filliformas is a parasitic native plant. It just looks invasive in the places where it’s all over everything. Wild South Florida says it’s the plant world’s version of a vampire bat, sucking the life out of its host. Halloween is coming in South Florida.

Last bird of our one hour walk, a Northern Mockingbird, perched in a ray of sunshine.

I found out about this walk through the Happenings page of Audubon of Martin County’s website: HERE.

Club Scrub-Jay

DSC_2484

Cool lake on a hot day at Jonathan Dickinson State Park, last Sunday, when I went on a solo trek to find scrub jays.

DSC_2485

I walked around this lake. It smelled a bit like a northern freshwater lake – cool, fresh, watery and alive!

DSC_2487

This narrow trail was shared by mountain bikers. Best to choose the trails marked for foot traffic only, I learned.

DSC_2489

Jonathan Dickinson preserves a large area of Florida scrub habitat.

DSC_2491

Florida sand pine scrub is an endangered subtropical forest ecoregion found throughout Florida in the United States.[4] It is found on coastal and inland sand ridges and is characterized by an evergreen xeromorphic plant community dominated by shrubs and dwarf oaks. Because the low-nutrient sandy soils do not retain moisture, the ecosystem is effectively an arid one. Wildfires infrequently occur in the Florida scrub. Most of the annual rainfall (about 135 cm or 53 in) falls in summer. It is endangered by residential, commercial and agricultural development.

Can you see the mountain biker in the above two photos? There is an active club at the park, Club Scrub.

But count me as a member of Club Scrub-Jay! (They should start one, right?) Here’s a Florida Master naturalist who is a big fan…

Why the Scrub-Jay should be Florida’s state bird, with Eva Ries

It has a beautiful dusty-gray breast, it has a gray collar around the back, it’s blue up top with a gray eyebrow, and it has the most unusual call. When they call to their compatriots, they make a rrih! rrih! rrih-rrih-rrih!

They are not hard to find, when you are in their habitat. They are curious and the landscape is open.

Audubon…

This bird is noteworthy on several counts. It lives nowhere in the world except Florida, it has a complicated social system, it has been the subject of very detailed field studies, and it is threatened by loss of habitat. Formerly considered just a race of the scrub-jays found in the west, it is now classified as a full species.

DSC_2528

Breeds in cooperative flocks. Each nesting territory is occupied by an adult pair and often by one to six “helpers,” usually the pair’s offspring from previous years. These additional birds assist in defending the territory and feeding the young. Studies have shown that a pair with “helpers” is likely to raise more young than a pair without. Nest site is in tree or shrub, usually an oak, with sand live oak strongly favored.

DSC_2529

I saw a total of three scrub-jays but just focused on getting decent shots of this one, close by and in good light.

A bit jay-like appearance but without a crest. Here is the familiar and widespread (east of the Rocky Mountains) Blue Jay for comparison, from a little later that morning in the park…

DSC_2560 (1)

Blue Jays’ behavioral attitude seems a bit fussier and sassier, like they enjoy complaining and picking fights. I watched them a lot in New Hampshire, especially at my bird feeders.

The Scrub-Jay seems a bit more peaceful, even elegant, especially for a corvid. Although maybe I need to spend more time observing them.

Saving Florida’s Friendliest Native Bird Matters

For the past 2 million years, Florida has been home to a superlative bird found nowhere else on earth. These birds are remarkably smart, with extraordinary memory and perhaps even the ability to plan ahead. Highly social yet quarrelsome, they’re like the stars of an avian soap opera. And they’re as brash and curious as precocious kids. Many a jubilant birdwatcher has turned to find one mischievously perched upon their shoulder.

I also got close to a Yellow-rumped Warbler in a thicket, a winter visitor to Florida.

DSC_2544

The Yellow-rumped Warbler is the only warbler able to digest the waxes found in bayberries and wax myrtles. Its ability to use these fruits allows it to winter farther north than other warblers, sometimes as far north as Newfoundland.

DSC_2546

Yellow-rumped Warblers are perhaps the most versatile foragers of all warblers. They’re the warbler you’re most likely to see fluttering out from a tree to catch a flying insect, and they’re also quick to switch over to eating berries in fall. Other places Yellow-rumped Warblers have been spotted foraging include picking at insects on washed-up seaweed at the beach, skimming insects from the surface of rivers and the ocean, picking them out of spiderwebs, and grabbing them off piles of manure.

I bought an annual pass to Florida State Parks and I will be heading back to Jonathan Dickinson again soon!
