Thanks for the feedback Carmel. Great progress is being made in =
automating the recording, processing, and identification of night flight =
calls. Hopefully in a couple of years from now, people like yourself =
could host a monitoring station on their property that could be part of =
a nocturnal migration monitoring network.
Sorry to hear about the Alder Flycatchers. Hopefully, they will return =
next year.

John, I love your reports! Keep up the good work.
=20
One thing I've noticed at my place here this year, a total absence of =
Alder Flycatchers. I did hear one on the road, a km away, but normally =
here at the old homestead, there'd be two to three pairs breeding. This =
year, nada. And you know how loudly they call, it's unmistakable. So =
that gap in the birdsong here is conspicuous by its absence.
=20
Another area I check on as well had none. This area normally has three =
or four breeding pairs, and it's about 10 km from me.
=20
Not sure what to make of it. I miss my familiar friends when they don't =
show up. Total absence wouldn't just be normal attrition, as the =
breeding group here were probably of different ages, and started with =
one pair in an area with an ash tree as their central hangout. That and =
a myrtle shrub, right by a huge alder patch. They were successful there, =
and expanding in the past few years, as I imagine their offspring =
returned and set up house not far from the nest they hatched in. So it's =
a loss. Not sure if anyone else has noticed a difference in Alder =
Flycatcher occurrence this year?
=20
I have a feeling something befell this little group during Fall or =
Spring migration, there were so many hurricanes and storms last year, =
and they winter in central America and down to South America. Or maybe =
on the wintering grounds. Anyway, there were a lot of them here right up =
to the time they left. =

Keep up the research, John, it's one way we can get some kind of handle =
on numbers and tracking populations over time I imagine.

Hi All,
Early Shorebird Migration Monitoring. For six days, 7-13 July, I set up =
an AudioMoth microphone and recorder at the edge of Sandyland Ponds in =
Beaver River. This microphone does not reach as high into the sky as my =
regular, highly directional microphone for nocturnal migration, the 21c. =
However, I was running the microphone both during the night and in the =
early morning to detect the arrival of early migrating shorebirds. Being =
an omnidirectional microphone, the AudioMoth was a better match for the =
objective of detecting early shorebird migration in these coastal ponds.
=20
A total of 50 shorebirds were detected during the six days, most of them =
in the early morning rather than at night. The most abundant, as =
expected for these early dates, was Short-billed Dowitcher (19 estimated =
birds). Other shorebirds recorded included Least Sandpiper (11), =
Whimbrel (8), Greater Yellowlegs (3), Spotted Sandpiper (2), Killdeer =
(2), Willet (2), Semipalmated Sandpiper (2), and Lesser Yellowlegs (1). =
A Sora was heard calling on 12 July at 0237 hours.
My full-scale monitoring of nocturnal migration for the autumn of 2019 =
began on the night of 15 July 2019 at my usual monitoring station at =
Beaver River. This site, while only a couple of hundred meters from the =
coastal ponds, had just a few shorebirds throughout the week. These =
included 3 Least Sandpipers and 3 Spotted Sandpipers.
The first songbird in nocturnal migration was a Savannah Sparrow at 0142 =
hours on 22 July. A White-throated Sparrow followed about a half hour =
later and then 2 Yellow-rumped Warblers. These birds are not likely true =
migrants but are undertaking post-breeding movements across the =
landscape in search of foraging areas. In fact, the main migration of =
these three species comes relatively late in the autumn.
Follow the migration at Beaver River on my website =
<https://johnfkearney.com/category/nocturnal-migration-journal/> or on =
eBird at NFC Station Beaver River or NFC Station Sandyland Ponds.
