Crops & Clips: Birding Doldrums

On rainy days our back yard lake has attracted a few birds which brighten my COVID-induced social seclusion. Shooting through the window produces poor photos, but the behavior of some of our visitors can be interesting.

A Great Egret suddenly appeared, dashing from left to right along the lake margin as if late for dinner:

At the same time, my peripheral vision caught motion to my right. A Tricolored Heron was likewise speeding into an imminent head-on collision with the egret:

Tricolored Heron 01-20200606

Tricolored Heron 02-20200606

Neither changed course and it was only a near-miss. The Tricolored Heron just kept running along until out of sight to my left. The egret simply flew off to the right. What compelled them to move so purposefully in opposite directions? Beats me!

Now that spring migration is over and our local birds are quietly tending to nests and youngsters, the number and variety of birds is way down. I am a big believer in Bird Chaser's Recommended Daily Allowance of Birds (RDA-B).

The day just doesn't start off right unless I see at least my RDA of 20 species on a morning walk. Sometimes I get stuck at 19 and decide to hang around a little longer "just in case" one more shows up. During migration I sometimes hit the target before half way through my route, making me feel so "well nourished" that I do not even think about numbers.

Wintering Gray Catbirds were so numerous that they became a distraction. Then they suddenly disappeared:

Least Terns appeared just as the catbirds were departing:

In any season I can predict with certainty that I will see 10 species without even trying. The species mix will vary by season. Now that summer is arriving, the list will usually include a cardinal, mockingbird, two or three woodpecker species, blackbirds, grackles and an assortment of crows, ibises, herons and egrets. 

Some of the usually common birds may decide not to show up. I have had heron-free mornings and the reliable flickers or shrikes may suddenly become scarce. Three species of doves are locally common, but sometimes I may hear or see only one. 

Or, the normally predictable afternoon rainstorm may pop up early and cut my walk short, leaving me nutritionally deficient (and a bit frightened):

One morning I obtained a nice "two-fer," bagging a Red-shouldered Hawk and a V-shaped flock of ibises in one peaceful setting:

A closer look at the hawk:

Common Nighthawks are laying their eggs on the bare gravel along the trail. The female often flies out and rests in front of me to attract me away from her nest.

For comparison, the male has larger white patches on his throat, wings and tail:

The male nighthawk swoops low over my head, pulling up sharply to create a startling "boom:"

Killdeer are also patrolling their nesting territories:

Heavy rains have caused the lake to extend into the lakeside marsh...

...and spill over into the wet prairie. Seeking dry footing, the deer are moving in from the Everglades preserve. I encountered a White-tailed buck with a pregnant doe and her yearling fawn. They stopped and stared at me...

The buck lagged behind them:

Once on dry land, the buck looked back at me:

They grazed along the dry path:

The doe had long eyelashes:

Before sunrise, a line of thunderstorms over the ocean created a regular series of parallel shadows which coursed overhead and appeared to converge on the western horizon, creating a mirrored "second sunrise:"

Crops & Clips: Spring Migration

Birding during spring migration in southeastern Florida is usually less productive than in autumn. In past years there have been pleasant surprises. One of the best years was 2011, when I found nine warbler species one morning in mid-April. 

A highlight then was a Blackpoll Warbler:

Least Terns return to our lake on or very close to April 15 every year:

Their courtship rituals begin almost immediately:

Our Son-in-Law was born in Sagua la Grande on the north coast of Cuba, which spreads out about 100 miles south of Key West. His father speaks of seeing large numbers of colorful birds filling the trees in springtime, waiting for favorable winds to help them cross northward over the Straits of Florida. 

This phenomenon was portrayed dramatically in these Key West velocity radar images which I captured overnight on April 26, 2017. The echoes of migrating birds moving towards the radar are depicted in green, while those moving away to  the north are red:

Key West radar 0952 PM APR 25, 2017

Key West radar 0515 AM APR 26, 2017

At the same time that morning, the Miami Radar returned dense echoes passing overhead. Our home, indicated by the "+" mark, inland  between Miami and Fort Lauderdale, appeared to be in the middle of a mass migration:

Miami radar 0515 AM APR 26, 2017 

The results on the ground were not quite as impressive, though I did find 16 individuals of seven warbler species. I expected that birds would be dropping off the trees! In truth, the radar is also capturing the huge biomass "bloom" of insects which are mostly being blown along by the prevailing winds. 

This spring's migration has been rather disappointing. Prevailing winds from the southeast often direct the migrants towards the west coast of Florida and even across the Gulf of Mexico. Also, since migrating birds can fly up to 50 miles an hour with a favorable tail wind, they can pass over south Florida well before settling down at sunrise. 

My  most memorable warbler sightings this year were small flocks of Cape May Warblers, on April 19 and 28:

Cape May Warbler 02-20200419

Cape May Warbler male 01-20200428

Cape May Warbler male 02-20200428

FACTOID: "The Cape May Warbler breeds in boreal coniferous forests, where it sings, feeds, and nests high in the spruce canopy... Although the first illustrations of this species were based on birds taken in Canada, its English name refers to the locality from which Alexander Wilson first described the species—Cape May, New Jersey—where it was not recorded again for more than 100 years..." (Ref: Cornell Lab Birds of the World)

After a very dry winter and early spring, we are finally entering our wet season. Sunrises can be spectacular...

View from our back patio on May 6, 2020:

The sky had cleared by nightfall as the Full Flower Moon rose over our lake:

Before sunrise In the local wetlands, a thunderstorm along the Atlantic coast cast a shadow which arched over to the Everglades on the opposite horizon:

Early morning sightings

Sheltering in place during the COVID-19 pandemic interrupts the familiar routines which formerly made each day of the week special. Now the days flow, one into another. There are no "weekends," no choir practices or church gatherings, all the parks are closed. Grocery orders and even routine doctors' appointments are handled on computers and iPads. The highlight of most mornings is our walk into and around our local wetlands preserve. Here is a random sample of our encounters...

Blue-headed Vireo:

A White-tailed Doe graces the morning scene:

Fog lifts along the shore of the placid lake:

Very early one morning we were surprised when two Eastern Screech-Owls began calling along the path. One perched on a signpost for flash photos (I darkened its pupils in these two photos):

The second owl landed on the ground and my flashlight produced a "red eye" in this poor photo.  As with all owls, their pupils react independently of each other.

Owls have the uncanny ability to rotate their heads 360 degrees in an instant. The slow exposure created this funny "bottle owl:"

Florida normally has a dry season which lasts from late October into early May. This winter we experienced near-drought conditions. Water levels in our local wetlands had been unusually high almost all year around for the prior three years. High water dilutes aquatic prey and wading birds must range far and wide to find food. Trails which we have explored in the past had been flooded and inaccessible.   

Low water now allows me to walk some of the trails created by ATV riders out in the local Wounded Wetlands. I call this one the North Lakeshore Trail. It provides a unique view of a sunrise which softens the ugly scars left by the off-road vehicles  :

A few minutes later, the sun climbs into the open sky:

The low water reveals a labyrinth of ATV tracks through the woodlands, previously out of sight:
