Let's see if eBird observations support that; let's compare this year (on the right) to last year, and then to previous years combined.
Comparison of "Total" Dark-eyed Junco, East Kootenay, spring 2017 to spring 2018:
|check out the scale on the left: 2017 upper limit = 420, 2018 upper limit = 1000|
Comparison of "Abundance" of Dark-eyed Junco, East Kootenay, spring pre-2018 and spring 2018
|again, check out the scale on the left: pre-2018 upper limit = 2.6, 2018 upper limit = 6.5|
And they seem to be staying around a bit longer, rather than dispersing quickly to breeding territories. Maybe because the snow is on the ground later and melting not so fast?
I know they are "thick" in my little yard - a dozen hanging around every day for the past two weeks. There are still a couple of patches of snow back there but they seem happy and sing most of the day until late afternoon.
And yesterday I had quite a strange mix of birds. Besides the juncos, and usual American Robin, there was a Mourning Dove, a couple of Clark's Nutcracker, a Pileated Woodpecker, and a dozen Common Redpoll still! AND a Varied Thrush later in the day. (Redpolls seems to be holding back a bit this year. Someone else reported a hundred of them out on a prairie.)
Nature! Always interesting!
And thanks! to all eBirders for reporting! With so many more eBirders, we are going to be snowed under by volumes of data at this rate!
