[cobirds] Harris hawk? Adams county?
OK, I know this is an awful post because I don’t know the exact location and didn’t report it promptly. I apologize for that. I was driving north on I 25 today at around 1:30 PM when a dark hawk flew over the highway from west to east and landed in a tree. It was very dark and had rust wing patches and white rump. It was approximately 2 miles north of the C-470 interchange. It’s been in a very long day so I haven’t had a chance to go back and see where the Harris’s hawk had been in the last few days. I also can’t swear that this is a Harris’s hawk because I didn’t get a very good look at it. So, this falls into that for what it’s worth category.

Re: [cobirds] Yesterday's golden-plover event--and a question for Bryan Guarente
Cobirders, when Ted beckons... you get a really long email... So the question is: 1. Why did this situation bring more birds to the Front Range? *TL;DR* (Too long; didn't read) -- Super-short snarky answer just for Ted: it was the wind! The weather had a lot to do with it and which end of the cold front Colorado ended up on helped dictate that flow of migrants. Based on percentage of the total flow area behind the cold front compared to the overall flow, it looked like a 30-40% chance that birds would end up in the Front Range due to funneling or convergence. *Full version:* - *Why did this weather situation bring more birds to the Front Range?* Let's look through the computer models because it is sexier, and makes it easier for everyone to understand because I can give you data everywhere on the globe. One could also do this with satellite imagery, but it is harder to get you to see what I want to see, so I will work with the easier option. - https://earth.nullschool.net/#2018/10/14/Z/wind/surface/level/orthographic=-105,40,1706/loc=-105.000,40.000 That animation of a single time gives you the idea of what is going on that made Colorado a hotspot for any migrants yesterday. Any bird trying to make its way to the southeast from Canada may have started out with good intentions, but depending on which side of the flow it started from or ended up in over time, it had a strong chance of ending up heading toward the Front Range. The cold front itself is the "blue" area with no wind that curves from Lake Nipigon down through Iowa, Nebraska, then curving into Colorado. All of the airflow behind that cold front (to the north and west) is what we want to focus on. The flow had multiple possible end points at that time: near Lake Nipigon, along the cold front just south of Lake Superior, along the cold front in Iowa, or into the Colorado Front Range. The highest likelihood location for the birds to end up was actually along the Front Range. The percentage of the total area of that flow behind the cold front that was showing a distinct convergence into the Front Range was about 30-40% (guesstimated). So any birds within that 30-40 percentage of the total area had a strong likelihood of ending up in Colorado's Front Range. That means that birds ranging from Alberta through Montana, North Dakota, Minnesota, and western Iowa and then everywhere southwest of that behind the cold front, had a strong chance of ending up in the Colorado Front Range. The door was wide open so to speak. The flow was broad initially, then came crashing in on itself converging into a small area (Colorado Front Range). So think of this as your funnel for bird convergence. On the broad end, you put in any birds you'd like, then on the other end, you get a stronger concentration of birds because the winds they like to follow are forcing them together more over time. Other places are getting lower concentrations of migrants due to the divergence of the birds from their area into our area. This was only one snapshot of the winds at the surface though. For a period of about 12 hours, this was still the case around this. Earlier it was less convergent into the Front Range, but picked up, then maximized around the time I showed you earlier, then tapered off a little. Importantly though, the time I linked you to was right around sunset when the snow started to pick up all along the Front Range. This was a bonus for birders, hindrance for the birds. Both the sunset and the snowfall made this more important for the birds to get to the ground, and then they likely stayed the night to try their luck at adding some munchies in the morning. This is the time for American Golden-Plover migration. It also happens that the location this storm started from had a good chance of grabbing some of those migrant AGPLs trying to make their way through the Central Plains like they normally do. However, as luck would have it, they ended up on the wrong side of the flow behind that cold front. They got stuck on the Colorado Front Range side, and then we got lucky to see them here. The number of AGPLs that migrate through this corridor in a short period of time is HUGE. That also gives us a higher chance of getting them here in CO. I remember from my days in Illinois that this time of year would produce fields upon fields of AGPLs numbering in the thousands easily. They would take off in huge flocks and migrate quite broadly through the area during the day. You could easily go a day with seeing 20-40 flocks numbering 500-1000 birds a piece. It is kind of surprising that there weren't more AGPL found along the Front Range when you think of it that way. Yes, you may say as a counterargument to my arguments about the wind that birds have wings, and they don't have to follow the winds. True. They don't have to follow the winds. If you ended up on the wrong side of that flow though (the west side closer to Montana or Albe

Yesterday and again this morning I saw a White-throated sparrow on the Homestead trail off of the Smokehouse Lane path access. It was flying to my yard as well. Easiest to park near 5331 Smokehouse lane and walk the trail access to the path below. This is about six houses south of North Carefree Circle and where the Homestead trail crosses it. There is a lot of road construction on N. Carefree and roads are often blocked. My yard has chain link fence you can see through.

[cobirds] Yesterday's golden-plover event--and a question for Bryan Guarente
Hey, everybody. American Golden-Plovers were reported from eleven (11) sites in Colorado yesterday, Sunday, Oct. 14. To put that in perspective, there were two (2) previous reports for Colorado in 2018: one (1) in Washington County, Sept. 4-8, and one (1) in Kiowa County, Sept. 18. The previous analysis is based on eBird data-mining. When one ponders such matters, one's thoughts turn instantly to Bryan Guarente. Bryan, what caused this? The snow, obviously. But why this particular snowfall? And why this particular species? Ted Floyd Lafayette, Boulder County P.s. Other than an American Golden-Plover, goodies yesterday in the general vicinity of Waneka Lake, Boulder County, included an Eastern Bluebird, hundreds of southbound Sandhill Cranes, two Hermit Thrushes, FOS Gray-headed and Pink-sided juncos, FOS Townsend's Solitaire, a Long-billed Dowitcher, Wilson's and Orange-crowned warblers, a getting-latish flock of 15 Lesser Goldfinches, and a Wood Duck. P.p.s. This Monday morning, Oct. 15, a quick stop at the Legion Park overlook revealed the Valmont Reservoir complex to be very birdy, harboring a Sanderling, a Semipalmated Plover, a couple dozen Mountain Bluebirds, and distant gulls, geese, and grebes galore. It would be very much worth the effort, I suspect, to walk in from Red Deer Drive and watch from the Open Space tract beyond the end of the road. -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
