I’m getting more BH grosbeaks showing up, both males and females and the female RW Blackbirds are here now also. I’m ready for the Evenings to leave, but I think they feature the Tractor Supply Sunflowers.
For anyone Interested the International site Crane Foundation is doing webinars on, wait for it, cranes. Last weeks was on western Sandhills and this week is climate change effects on cranes. Check their web for details.
One thought I have is a belief that feeder watchers way undercount the birds they see. The think the two Mountain Chickadees are the only two in the area while it’s likely a whole lot more are around, but we' unaware of numbers beacuse the speedy guys look the same.
Brian and I have traded emails on this for years. I think he has many more hummers than he thinks whennhe counts feeder visits. The advantage of hummers is ther is little competition for the sugar water in our area and you can measure how much they consume and use factors for rough number counts. I see maybe 30 hummers I think at the feeders in July and August, but the sugar depletion says 400-500 are using my five feeders.
I think think feeder birds are much mjore abudant than we think assuming we count them at our feeders as single individuals , let alone knowing how many of the ornery buggers bypass our offerings.

> There's been a change today in birds. Cassin's Finch numbers are down to just 3-4, all females. And Evening Grosbeaks have decreased to about a dozen from a high of 30. They're about evenly split, male to female. There are more Yellow Warblers & Lazuli Buntings appearing. Also, a small flock, 4-5, Cedar Waxwings showed yesterday.
> More male Black-headed Grosbeaks are appearing at the feeder now. A new bird for the season today was a Ruby-crowned Kinglet. And, both a male & female Black-chinned Hummingbird are hitting the nectar feeder, but not at the same time. There's a Sharp-shinned Hawk which keeps the Eurasian Collared Doves greatly thinned. I rarely see more than 2-3 at a time & find a pile of their gray dove feathers about every 10 days or so. During the winter, the Sharpie adds an occasional Junco to his diet. The Blue Jay was here yesterday but haven't seen today.
