The eagles have landed, but...

There is drama at the local Bald Eagle nest. I have been observing the nest since it was "discovered" back in 2007. Over the years, the same male "Pride" has fathered 27 known eaglets, of which all but eight survived to fly freely. Pride's first mate was Joy, who disappeared just before the 2014-2015 breeding season after producing the first 13 eaglets, of which only two did not survive to fledge. 

Pride then paired up with Jewel in December, 2014 but it was either too late in the season, or she may have been too young to breed.  However Jewel went on to hatch out 14 more eaglets. As of now she has lost 6 of them. Two (and probably their newly hatched unseen nestmates) were assumed to have been killed in 2016 and 2020 when early spring storms disrupted the nest. In both seasons the pair went on to raise second broods of two eaglets. They lost one of these to unknown causes in 2016, but successfully raised both in 2020. 

Those two youngsters hatched 2-3 months later than usual. In normal years they would have fledged in April or May, but these two were dependent upon their parents well into late summer. This probably delayed the start of the 2020-2021 breeding season, which usually begins around October 1. The pair worked to build a new nest in a very precarious location, high in a limber Australian Pine with only two major supporting limbs. 

Eggs are normally deposited by early December and hatch in early to mid-January. Instead, their first egg was laid around February 1, 2021 and two eaglets hatched around March 7-12th. Normally the eaglets fledge at about 10 weeks of age.  A severe thunderstorm on April 11 damaged the flimsy nest and a week later the younger eaglet fell to the ground. The older sibling fell on April 28 and was recovered after 5 days of searching. 

Both eaglets suffered broken bones, but the injuries to the younger bird (P Piney 27) were more serious and eventually fatal, while the older sibling (P Piney 26, a male) was successfully rehabilitated and released to the wild on June 14. It was sad to see Jewel visit the site of the demolished nest several times during the summer. Suddenly Pride showed up and joined her on  Freed from the burden of rearing any eaglets, they instituted courtship and began rebuilding the failed nest.

On September 11. Pride occupied a dead branch near the site of the original (old) nest, about 100 yards away:

Jewel was roosting above the remains of the failed nest. This was not a good omen. Some researchers report that the female more frequently chooses the nest site. Her position corresponded to the placement of the main nest platform (bole). The empty space under her had been occupied by nesting material which collapsed during the storm and began the process resulting in the grounding of both eaglets: 


The next day, both adults were carrying sticks and exhibiting courtship behavior with copulation attempts. On the morning of September 14 the eagle watchers saw Jewel fly into a tree and attempt to break off a large dead branch. It would not budge...

...so she settled for a smaller one, indeed a twig...




...and added it to the sparse material already deposited in their restorative effort:

Some of the structure of the failed nest is still lodged below its original site. The nest was placed between the main trunk and a single side branch. We are not very optimistic about their chances this breeding season:

She then roosted nearby and Pride flew in to join her. They perched shoulder-to-shoulder. Jewel is to the left in these photos. Note her very long rear talon (hallux), a distinguishing characteristic of the female:



Both called together. Their fixed fierce facial expressions made the lovers' interaction look more like a hostile encounter: 

Fall migration is getting off to a slow start. Prairie Warblers have migrated "sideways" from their coastal breeding habitat:

Crops & Clips: Flashback to September, 2018

As I do each month, I enjoyed looking back over my archived photos, taken three years previously, to remember how things were then and maybe get some idea of what to expect this year. As usual, I searched for images which reflected favorite memes: critters of all kinds (especially birds), skies and clouds, reflections, flowers and fences, as well as scenes which speak for themselves. 

We started the month at home in Florida. Southbound fall warblers were starting to pass through, but prevailing winds directed most of them to the west (Gulf) coast. My warbler photos were limited to--

Louisiana Waterthrush:

Prairie Warbler:

Female Common Yellowthroat:

Black-and-White Warbler:

In the rookery (which has since been essentially abandoned), a Yellow-crowned Night-Heron roosted in a tree which would soon be cut down:

A tiny Bella or Rattlebox Tiger Moth rested on a blade of grass:

When is a goose not a goose and a duck is not a duck? Two gooselike members of the avian Order of Anseriformes (Ducks, Geese and Swans) enjoy rather uncertain positions as to where they fit into the classification scheme. Both bear some resemblance to each other and to the Shelducks, a group of large ducks which are smaller than geese. 

Male Muscovy Duck and Egyptian Goose (Drakes or Ganders, take your pick) posed nicely in our back yard, exhibiting rather similar characteristics of heavy bodies and thick goose-like necks. Both of these introduced exotic species are populating the urbanized areas of south Florida.

We visited our daughter's family in Illinois, our first return after selling our condo. Wasting no time, we headed to Nelson Lake, our favorite hot spot. In the prairie, Milkweed Bugs clustered on a seed pod of their host plant:


Fall flowers turned the fields to yellow:



A stately old oak at the edge of the golden prairie hosted Red-breasted Nuthatches which earned their nickname of "upside-down birds:"


I applied "oil painting" effects to this photo of a red barn and silo across the road from the preserve (click to enlarge):

By the end of the month we were back home in Florida, where a juvenile Green Heron provided evidence that at least some of the herons had nested successfully in the rookery:

It was a good month for flight shots, this of a Tricolored Heron...

...a Red-shouldered Hawk carrying prey...

...Great Egrets...

Beauty is in the eye of the Barn Owl

I first encountered a Barn Owl in our local wetlands preserve in 2015, when I saw one on the top of a dead Royal Palm along the gravel entry path. That tree was subsequently removed and replaced by another which also died.  

According to Cornell University's global eBird database, this species has never before been reported to breed anywhere in southern Broward County. The nearest historical sightings occurred in undeveloped areas in Miami-Dade County about 4 miles / 6.4 kilometers to the south.and in Broward County 10.5 miles / 17 kilometers to the north. I never saw another until I photographed one in flight near this location in February, 2019.

Since then they have been present consistently. These are earlier photos:

Here is the topless palm tree in an undeveloped spot where I first saw a Barn Owl, in August, 2015:

Although I never saw them again until 2019, I was encouraged when I found this wing feather in October, 2018, very close to the old tree:

I suspected that they may have been nesting on the top of another Royal Palm behind a home across the gravel road. This tree had also died and lost its foliage. I heard and recorded a young owl nearby only a few weeks ago (Link to eBird checklist)

This species nests all year round. This week there were two Barn Owls occupying the top of this second tree, too dark for my camera, so here is the daytime view (along with our neighbor's  regulation-compliant fence):

Our homeowners association contracts with landscapers to maintain the area along the berm where the nest tree is located.  Many people cannot stand the sight of an old dead tree and I feared they may be planning to remove and replace it with a more "fitting" representative of our refined community. The Barn Owl does not see it this way.

Therefore, I worked with the homeowners association on a plan to to protect the nest tree. A pair of Barn Owls and their brood can eat as many as 3,000 rodents in a single nesting season, so they are much more efficient than a pest control company. While they are protected by the Federal Migratory Bird Treaty Act and they are the least numerous among Florida's 5 owl species, they are not threatened or endangered. 

Happy to say that my mobility and energy have vastly improved since starting on Prednisone. MaryLou and I have been out about an hour before sunrise almost every morning. We arranged for Juan, a fellow birder to meet us on the way in and he was treated to seeing both Barn Owls as they emerged from the palm trunk and flew overhead, their pure white undersides reflecting the glare of our flashlights.

As we were observing the Barn Owls we heard an Eastern Screech-Owl calling nearby. Juan located it and I obtained poor photos with the help of his flashlight:

That day I logged over 10,000 steps for the first time in almost a month as we trekked into a more primitive area of the preserve on the Bar Ditch Trail. As we walked westward, Juan turned around to capture the rising sun:

Were it not for the sound of airplanes and distant traffic, we could have been lost, deep in the wilderness:

Back home and in seclusion, we enjoyed a visit from the mamma Muscovy Duck, who hatched out 15 ducklings in our back yard. She now was guarding the last four survivors of her brood. Turtles, bass, cats, herons and hawks are not kind to baby ducks:
