This last week in September is usually the peak of the season here. Despite lots of rained-out nights, we’ve had a few good nights over the last week. 19 Northern Saw-whets banded tonight so far, and 4-8 owls banded most nights over the last week.

Two Boreal Owls have been banded so far, which is up from last year (only one banded), but far from years like 2011 (56 Boreals banded) or 2017 (48 Boreals banded). Boreals tend to come later in the season, so more might be on their way.

Totals for the season so far:

After 15 years, we finally caught our first owl that was banded somewhere else.

This hatch-year Northern Saw-whet was originally banded in Anchorage. It was banded in a nest box in Forsythe Park in May 2024.

There have been quite a few rained-out nights so far this season; hopefully conditions improve.

At the suggestion of a couple of friends, I finally scraped together enough parts from the junk drawer to put together a BirdNET-PI system. This is a Tensorflow-based machine learning system that listens to the audio stream from an outdoor microphone and can identify over 6000 species. A station can be set up inexpensively; all that is needed for a minimal system is a Raspberry Pi board and an outdoor microphone.

This new station’s results can be seen on Birdweather:

The results are pretty impressive so far, although I’ve seen a few false detections- the local squirrels are being detected as Belted Kingfishers.

The system is configured to ignore detections of Northern Saw-whet Owl, Boreal Owl, and Western Screech-owl for now since the owl banding operation uses audio lures of those species- no need to pollute the BirdNET results with our lure playback.

Owl banding time again.

The owl banding station here in Homer, Alaska was set up during the last week of August. Same small setup as previous years- four nets total.

We’ve opened nets eight nights starting August 22, and we’ve been rained out six nights so far.

As of Sep 8, we’ve banded 15 hatch-year Northern Saw-whet Owls.
