Start of 2022 banding season

The banding station is up and running for the Fall 2022 season.

The official start date is Sep 1, but an early test netted one Northern Saw-whet on the night of August 28. This was a hatch-year bird.

Starting Sep 1, I’ll be opening the nets every night that weather permits.

Thanks to Betsy for the help with station setup, and to Jess for visiting the setup on Sunday night!

Still catching owls most every night that weather allows. Nets have not been opened on several nights this month due to rain/wind/snow/ice.

More owls showing up over the last week- and a meteor

Banding has picked up a little over the last week or so. Although it’s still a comparatively slow season, I’ve been banding at least a few owls every night lately.

Sep 294 Northern Saw-whets banded; 2 hatch-year, 2 adults
Sep 284 Northern Saw-whets banded, all hatch-year
Sep 276 Northern Saw-whets banded, all hatch-year
Sep 269 Northern Saw-whets banded, all hatch-year
Sep 256 Northern Saw-whets banded, 1 adult, 5 hatch-year. Also first Boreal Owl of the season.
Sep 241 Northern Saw-whet banded, hatch-year
Sep 222 Northern Saw-whets banded, both adult (second-year)

And tonight, at almost midnight, a bright green meteor lit up the sky while I was out checking the nets. I had never seen one quite so bright/close. A couple of minutes later, a loud, distant explosion was heard from the north. It should be interesting to learn more about this event; I’ve already heard of other sightings around Homer and from communities to the north.

Back to banding

The owl banding setup is up and running again with a brand new set of nets. Nets have only been open a few nights over the last week due to weather; still slow-going but a few owls are starting to show up:

Sep 193 Northern Saw-whets banded, all hatch-year
Sep 185 Northern Saw-whets banded- 3 second-year and 2 hatch-year
Sep 177 Northern Saw-whets banded- 3 adults, 3 hatch-year;
1 returning Saw-whet originally banded in 2020

Banding pause- due to moose

It’s been a slow season start so far, with only 5 new Northern Saw-whet Owls banded and 2 returning owls from last year.

But things came to a halt tonight at the first net check- I found the whole setup demolished as three moose (who apparently don’t like mist nets) went running into the woods.

Three of the four mist nets in the setup were completely destroyed. One net may be salvageable. Time to place another order with Avinet; two of the destroyed nets were new this season and hadn’t even caught an owl.

Hopefully I have enough old nets, probably full of holes, to set up tomorrow while I wait for new nets to arrive.

Slow start to 2021 banding season

The 2021 owl banding season here in Homer, Alaska is off to a very slow start.

Nets have been open (weather permitting) since Aug 20, but before last night, only a single owl had been caught- a returning 2nd year Northern Saw-whet Owl that was originally banded here 366 days earlier.

Last night, three owls showed up- all Northern Saw-whet adults. One was another 2nd year bird with a band (again, banded here exactly 366 days earlier); the other two were after-second-year adults.

So far, NO hatch-year birds have been banded during this season, making this season start the slowest in 12 years of banding here.

End of season totals

The 12th season of fall owl banding was concluded on Oct 31 for the season. Only a few owls were banded during the final week.

A total of 304 owls were banded, making this season the 2nd best here so far.

292 Northern Saw-whet Owls were banded, the largest number in a season yet. The age breakdown was as follows:

Hatch-year28597.6%
Adult72.4%

Additionally, three Saw-whets banded in previous years here were recaptured.

12 Boreal Owls were also banded. All Boreals banded were hatch-year birds.

Over the 12 years of banding here, Saw-whet numbers have ranged from as low as 20 to as high as 292 banded in a season. Boreal numbers have ranged from as low as 3 to as high as 56 banded in a season.

Slowing down for the season; 300th banded

Banding has slowed down over the last week, with 2-3 owls banded per night. Temperatures are going below freezing at night, and the nets have been frosted up by about 11pm on several nights.

The 300th owl for the season was banded tonight. So far, the total (301) includes 289 Northern Saw-whet Owls and 12 Boreal Owls.

I forgot to take a photo of the 300th owl, so here’s the 301st, a hatch-year female Northern Saw-whet.

Best year so far for Northern Saw-whets

This season’s 265th Northern Saw-whet Owl was banded last night. This makes 2020 my best banding season yet for Saw-whets; the previous top season was Fall 2011, with 261 Saw-whets banded.

It remains to be seen whether or not 2011’s overall total of 317 banded owls will be surpassed. 2011 was also a good year for Boreal Owls, with 56 banded. Only 9 Boreals have been banded so far during 2020, but there are still a couple of weeks left in this season (I usually close things up at the end of October).

Continuing rainy weather has made banding slower during the last week. I’ve typically been banding 5-10 owls per night when it wasn’t raining.

2000th owl banded

The 2000th owl banded during 12 banding seasons at this location arrived tonight. Owl #2000 was a hatch-year Boreal Owl.

Seven Saw-whets and two Boreals were banded tonight after a relatively slow week- I only banded during a few nights over the last week due to near-constant rain. Totals for the season at this point: 233 Northern Saw-whets and 7 Boreals banded, plus three returning Saw-whets banded in previous years.

A large Northern Saw-whet banded this week- 118.2g, one of the heaviest I’ve seen here.

Although the Saw-whets seem to be slowing down, Boreals seem to be picking up- 4 of the season’s 7 were banded in the last 3 days. Another was seen watching the proceedings as the nets were being closed tonight:
