Despite snow on the ground and pea soup fog at South Gap Lake in the Snowy Range (11,120 feet elevation), on Sept. 27 I saw a flock of dark-eyed juncos. They like snow. Usually I see the first ones down in my yard mid-October, when alpine winter conditions get too rough.
Juncos are those little gray birds that come in five subspecies and multiple hybrid colorations in Cheyenne, but they all have white outer tail feathers. They are my sign of the start of the winter bird feeding season–and the Project FeederWatch bird counting season.
Project FeederWatch is a citizen science opportunity for people with bird feeders to count the birds they attract as often as once a week (or less) between November and early April. Begun in Canada in 1976 and in the U.S. in 1987, more than 20,000 people participated last year. Data are used in scientific studies, many of which are summarized on the project’s website.
Participation costs $18. You receive a research kit, bird identification poster, the digital version of Living Bird magazine and the year-end report.
If you feed wild birds or are considering it, you must visit the Project FeederWatch site, https://feederwatch.org/, whether you register for the program or not. It is now beautifully designed and packed with information.
For instance, in the “Learn” section, I can find out juncos prefer black-oil sunflower seeds–and seven other kinds. I personally stick with black-oil because it’s popular with many species in Cheyenne. I also learned juncos prefer hopper-style feeders, platform feeders or feeding on the ground.
Seventy-one species are listed as potential feeder birds in the Northwest region, which stretches from British Columbia to Wyoming. However, about 15 of those species have yet to be seen in Cheyenne, so click on the “All About Birds” link to check a species’ actual range.
The Project FeederWatch website addresses every question I can think of regarding wild bird feeding:
–Grit and water provision
–Window strike reduction
–Tricky identification, like hairy vs downy woodpecker.
In the “Community” section you’ll find the results of last season’s photo contest, participants’ other photos, featured participants, tips, FAQs, the blog, and the FeederWatch cam.
I find the “Explore” section fascinating. This is where you can investigate the data yourself. The “Map Room” shows where juncos like to winter best.
Based on last season’s data, in the far north region of Canada, juncos were number 12 in abundance at feeders. In the southeastern U.S., they were number 13. However, in the southwest, which has a lot of cold high elevations, they were number two, as they were in the northeast region, and number three in the central region, the northern Great Plains. Here in the northwest region, they were number one. We have perfect junco winter conditions, not too cold, not too warm.
However, looking at the top 25 species for Wyoming in the same 2016-2017 season (based on percent of sites visited and the average flock size), juncos came in fifth, after house sparrow, house finch, goldfinch and black-capped chickadee. Other years, especially between the seasons beginning in 2007 and 2013, they have been number one.
I looked at my own Project FeederWatch data to see if I could spot any dark-eyed junco trends.
I get in 18-20 weekly counts per year. In the past 18 years, there were three when the juncos missed none or only one of the weeks, in 2001, 2005 and 2008. Those seasons also happened to be the largest average flock sizes, 8.65 to 9.72 birds per flock.
Later, there were three seasons in which juncos came up missing six or seven weeks, 2011, 2013 and 2016. Two of those were the seasons of the smallest average flock sizes, 1.6 to 2.5 birds per flock.
It appears my local junco population was in a downward trend between 2008 and 2016. Let’s hope it’s a cycle. Or maybe our yard’s habitat has changed or there are more hawks or cats scaring the juncos away. Or some weeks it’s too warm in town and they go back to the mountains.
One yard does not make a city-wide trend, but we won’t know what the trend is unless more people in Cheyenne participate.
How many FeederWatchers are there in Cheyenne? We’ve had as many as four, back in 1999-2004, but lately there’s only been one or two of us. Statewide, Wyoming averages 25 participants per year.
If you sign up, you’ll have your own red dot on the map (but your identity won’t be publicized). I hope you’ll become a FeederWatcher this season.
