John, I love your reports! Keep up the good work.
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 t=
he 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 bi=
rdsong here is conspicuous by its absence.
Another area I check on as well had none. This area normally has three or f=
our breeding pairs, and it's about 10 km from me.
Not sure what to make of it. I miss my familiar friends when they don't sho=
w up. Total absence wouldn't just be normal attrition, as the breeding grou=
p here were probably of different ages, and started with one pair in an are=
a 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 pa=
st few years, as I imagine their offspring returned and set up house not fa=
r from the nest they hatched in. So it's a loss. Not sure if anyone else ha=
s noticed a difference in Alder Flycatcher occurrence this year?
I have a feeling something befell this little group during Fall or Spring m=
igration, there were so many hurricanes and storms last year, and they wint=
er 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 le=
ft.=C2=A0
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, h=
ighly directional microphone for nocturnal migration, the 21c. However, I w=
as 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 detectin=
g early shorebird migration in these coastal ponds.
=C2=A0
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 Ye=
llowlegs (3), Spotted Sandpiper (2), Killdeer (2), Willet (2), Semipalmated=
Sandpiper (2), and Lesser Yellowlegs (1). A Sora was heard calling on 12 J=
uly at 0237 hours.
My full-scale monitoring of nocturnal migration for the autumn of 2019 bega=
n on the night of 15 July 2019 at my usual monitoring station at Beaver Riv=
er. 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 San=
dpipers and 3 Spotted Sandpipers.
The first songbird in nocturnal migration was a Savannah Sparrow at 0142 ho=
urs on 22 July. A White-throated Sparrow followed about a half hour later a=
nd 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 or on eBird at NFC Stati=
on Beaver River or NFC Station Sandyland Ponds.
John
