Dusty Blue Moon

Last weekend we celebrated a rare  Seasonal Blue Moon. The usual Blue Moon occurs when there is a second full Moon in a single month. The second during any one of the four seasons is called a Seasonal Blue Moon. The latter is a bit less frequent, but both happen about every two or three years. Both may rarely occur in a single year, as happened in 2018, but this will not be seen again until 2037, a few days before my 102nd Birthday. 

When there is a full Moon, we enjoy getting out early to watch it set into the lake from a vantage point about a 15 minute walk from our home. Best viewing occurs during the half hour before moonset, but on Saturday morning it was too early for us. The  nearly-full Moon set around 6:00 AM and disappeared from the clear sky just as we started out on our walk. 

Steven, a friend and very accomplished birder, accompanied me. As usual, MaryLou broke ranks and power-walked a mile out and we were only about halfway in when, on her way back home, she blew past us in the dark. Steven sought three target birds. The first was the Barn Owl, which we encountered very soon. A pair have been breeding in the hollow tops of dead Royal Palms. I "discovered" them in 2015, but did not find nest #1 until 2019. They occupied nest #2 this past breeding season, raising one owlet which fledged in February. For the past month the pair have been roosting on a third dead palm just to the north of nest #2. This was where we heard and then saw it on Saturday. Much too dark for photos.

A Chuck-wills-widow, the second of Steven's target species, treated us to a nocturnal fly-by. Again, no photos.

We reached the extinct heron rookery before sunrise. An unseen Green Heron called out. Steven caught sight of a cluster of three Yellow-crowned Night-Herons high in a tree and silhouetted against the brightening eastern sky. My best photos were horrible:

As the sky brightened, Steven's eagle eyes spotted (yes, an immature Bald Eagle, but also) what, at first, appeared to be a large nest. On closer inspection, it was a family of Raccoons. As their parents remained curled up asleep in the branches above them, two youngsters stared back intensely:

A few days earlier, on August 16th I had located an Alder Flycatcher near the entrance to the Wounded Wetlands. This was the priority bird for Steven, but it failed to appear this morning:

Steven did locate a Great Crested Flycatcher which I had overlooked:

The next morning I hoped to photograph the setting of the Blue Moon just before sunrise. However, it was barely visible through the murky sky, tinged brown by a huge cloud of Saharan dust:

Other sightings this past week have been a Monarch butterfly on the flowers of Firebush:

On August 16, before the dust storm, we enjoyed a pastel sunrise:

Fall migration is underway

Being out early in the open nearly every day over the years has attuned us to astronomical events-- the oppressive heat of mid-morning Sun, the phases of the Moon, the shifting length of days, and even the angle cast by our shadows. Commonly at dawn, not a ripple mars the surface of the lake. On September 17 the Harvest Moon set on such a morning:

 

We start our walks facing due west, and follow a gradual 90 degree curve to true north. My first stop is at a small peninsula which juts out westward into the lake. Just after sunrise, it acts as a sort of sundial of the seasons. With the Autumnal Equinox approaching my shadow falls full on the path ahead. 



The sun will soon rise within the frame created by the back gate of the adjoining subdivision directly east of this location:



Migratory birds began appearing a few weeks ago, providing a departure from the uniformity of the summer bird population. Shorebirds are often the earliest arrivals. This year we saw few, as there are no extensive mud flats because of the high water levels. The little peninsula path has sometimes been under ankle-deep water.

Spotted Sandpiper showed up first, on September 12. Note its pronounced eyebrow line and how the white of its breast extends up in front of the shoulder:



I heard the distinctive call of a Lesser Yellowlegs a few days earlier, but finally saw one flying over, on September 13:



Here is a side-by-side comparison of Greater and Lesser Yellowlegs, taken back in 2014. In addition to its larger body size, the bill of the Greater Yellowlegs (in background) is longer and curves slightly upwards. Two Least Sandpipers may also be seen, to the left in this photo:



Least Sandpipers followed on September 15:



A Solitary Sandpiper appeared on September 17:



The Spotted and Solitary Sandpipers are rather similar in appearance during the winter, when the former species loses its breast spots. They are present in this unusual side-by-side comparison of the two species,  back in the spring of 2015:



We have only two regular resident warbler species, the Common Yellowthroat and the Prairie Warbler. As fall approached, their populations were gradually augmented by arrivals from the north.

This is a female Common Yellowthroat in a Firebush (Hamelia patens) on September 17. The male has a striking black mask:



Prairie Warbler, also photographed on September 17:



Other arriving warblers included the Black-and White Warbler (September 7)...



...Yellow-throated Warbler (August 20)...



...an Ovenbird (September 17)...



...Northern Parula (September 13)...



...and, among other warbler species, the American Redstart. This is an adult female, in which yellow replaces the fiery red in the adult male's plumage (September 16):



A Red-eyed Vireo provided a pleasant photo-op on September 17):



Some flycatcher species came in early, notably the Eastern Kingbird (September 5):  



We are within the Great Crested Flycatcher's breeding range but do not see them until they wander after nesting (August 20):



This is a diminutive member of the Alder/Willow Flycatcher complex in the Empidonax family. These two species can be distinguished from each other by their calls. Unfortunately, this specimen was silent (to my ears) but over a 7 day period readily responded to the recorded call of the Alder Flycatcher and ignored that of the Willow. Finally I obtained a recording of its voice, which clinched the identification as an Alder Flycatcher (September 9):



Blue-gray Gnatcatchers can become so numerous as to be a distraction, but their antics are fun to watch and they often are accompanied by other migrants (September 6):



Other migratory treats so far have been a Merlin which I spotted as it roosted along the path in semi-darkness about 20 minutes before sunrise on September 18. 

Because of the poor light (Camera settings were 300 mm lens at f/4.0, ISO 3200, exposure 1/40 sec, exposure compensation +2/3) my hand-held image of this small falcon is a bit soft :



A Peregrine Falcon was an even more challenging subject, as it was nearly a quarter of a mile away (September 14):



An immature Black Skimmer flew in on September 15, the first ever reported in our birding patch: 



Mockingbirds alerted me to the presence of an immature Baltimore Oriole by chasing it out into the open on September 16:



A European Starling had a vociferous confrontation with an exotic bird that probably "migrated" from its cage (September 3):



It was a Yellow-collared Lovebird, native of east Africa (also known by a variety of other names in the pet trade):



Not to be overlooked, Monarch butterflies are passing through on their multi-generational pilgrimage to Mexico. This one poses on a Duck Potato flower (September 17):



Here is an earlier photo of a Monarch, accompanied by a honeybee, on Ixora blossoms (January, 2015):
