Nellie remains underwhelmed by such things, but I maintain that a #redtailedhawk riding a #thermal in a cloudless sky is one of the most beautiful things I've ever been privileged to experience on this, my favorite planet.

Mixed flocks of blackbirds are my bane
Просмотров 45121 день назад
On any other day I could drive by and remark, "Wow, that's a lot of blackbirds." But on the #ChristmasBirdCount, it's my job to actually count 'em! Despite my initial reaction in the clip that these were mostly #Brewer'sBlackbird, I had it reversed: My final count was just 230 Brewer's and a whopping 2020 #BrownHeadedCowbirds. #Audubon #CBC #wildlife #Oklahoma #birds #birding #ornithology
Northern Harrier on the wing
Просмотров 4921 день назад
Enjoy these 37 seconds of a Northern Harrier coursing over an Oklahoma field in December 2023. Note the behavior - rarely do any other North American raptors fly like this (Short-eared Owl comes closest), the shape with its wings held above horizontal and its long tail, and of course that big, bold white patch on the rump. #NOHA #NorthernHarrier #wildlife #birds #biodiversity #Oklahoma #birding...

There are no uninteresting #corvids. Here I'm enjoying a stroll at the #YMCA of the #Rockies in #EstesPark, #Colorado whilst on campus for the 2024 annual meeting of the #AmericanOrnithologicalSociety. Autumn visitors are attended all day long by mixed flocks of #AmericanCrow and, featured here, #BlackBilledMagpie. They're bold, intelligent, crafty, and gorgeous, and folks in the eastern US are...

Something weird happened here in #Stillwater, #Oklahoma on Sunday, 11 August, 2024: It was cool and rainy! Stillwater received nearly 2" of rain. It felt heaven-sent. Here's about 44 minutes of #ambient #rainsoundsforsleeping , occasional peals of #thunder, my cat, and birds outside including #CarolinaChickadee, #tuftedtitmouse, #AmericanCrow, #MourningDove, and #NorthernCardinal. Oh, and there...
Pecan cache revealed by spring Rx fire
Просмотров 257 месяцев назад
All told, I've got about an acre of lawn here in Stillwater, OK, but each year I let about half of that go unmown in a series of pollinator patches. Come spring, I'll burn some of those patches. This year (2024) in one of those patches, burning off the 2023 vegetation revealed a bunch of pecans. This wouldn't be remarkable if the patch was beneath a pecan tree, but it was because it wasn't: tho...

An abundance of wild food for birds
Просмотров 5410 месяцев назад
So many folks ask me why there are "no birds" at their feeders. The answer is almost always the same: they don't need your food. In autumn, the abundance of fruits, nuts, seeds, and whatever insects might still be about means that birds won't really start coming into your feeders until the first really cold weather sets in. Those natural foods are usually depleted by spring and that can be when...

Any rusties in there? 👀
How you got thus input data ? For eg amy pipeline u used
😍OOH, SO VERY BEAUTIFUL OWL!!!!😇💚💖💜

Not nymphal ticks. These are larval ticks!
My dog recently wandered into a nest of seed ticks. He literally had hundreds upon hundreds of them on him.
just had this happen to me today and boy oh boy this shit sucks lol
Hello, I do not know where you are but it is happening here in East Texas as well. Picked a couple 5 gal buckets last week. Very early to me as well.
I heard one doing this once too!

Thank you so much!!!!!!!!❤
so pretty
it's pretty

死んでるの⁈😰💦
*Little cutie barred owl is dead???*
Yes, sadly. I found this bird as a roadkill. : <
Awesome video thank you!
Hes da biggest bord! 🤑🤑🤑
Can you feel them, or is this just a visual thing?
You can feel them, but it's really easy to not notice them until it's too late.
Thank you. Now I can model a barred owl wing
Awesome
Are those the eyes that we see inside the ear or giant ear drums?
Indeed they are!
Interesting clip
@@timoconnell2206 Indeed what?
@@iprot00 In the video, I move the flap of skin that is the external ear on a Barred Owl. Within that space is some kind of membrane stretched over something that looks fairly rigid, best seen ~1:25 mark. That is the back of the owl's eyeball. An owl's eye isn't just a big ball; it's kind of bell shaped. It's more of an eye-tube that flares out into the skull. So to clarify: those are eyes that can be seen inside the ear.
@@timoconnell2206 Ah, clarification, it's a beautiful thing.
My grandson & I were out walking near a business that had a big gravel area & field behind it & they all came sitting on the fence griping at us as we walked by. I guess defending their nests. I didn't know what kind of bird they were - had to research - but was surprised they don't nest on the ground like the Killdeer. Nothing else nearby except for the building for them to get so protective of. No idea where their nests were, but they sure did gather up to chirp at us as we walked by.
Many of the New World Flycatchers - e.g., kingbirds, phoebes - have adapted well to nesting on and around human infrastructure. Some of our busiest, multi-lane intersections here in Oklahoma have their own nesting pairs of Western Kingbirds or Scissor-tailed Flycatchers. A little ledge on a tower or utility pole, one scraggly tree -- that's all they need!
@@timoconnell2206 wow! I will keep a lookout!
Interesting 😍
WONDERFUL!!! You have helped me a lot
fascinating behavior
I love it when they do that! Watch them out my kitchen window, funny little birds!
The comb structure just mutes the noise or also slice through the air with less drag?
I think both - the drag reduction isn't needed for more efficient flight, but it is what's leading to the quieter flight.
I don’t like weed wacking either. 🦉 Took me a few to realize that inside joke…”who cooks for you? “.
Can this be used with percent cover of each species instead of total abundance?
Mathematically it should work so long as the individual per cent covers sum to 100 - be sure you're clear about percent (100) vs proportion (1.00) in calculations. BUT, be very clear in your application that you're not specifically comparing the same thing with percent cover as you are with abundance of individuals. One big leaf could cover a lot of area in a small plot. Conversely, entire individuals of various seedlings might occupy a really small area. I'd say percent cover is at best analogous to abundance. With those caveats, why not?!
I LOVE YOU!!!! THANK YOU!!! YOU SAVED MY LIFE
Hahaha -- YES, this is why I've put this out to RUclips. I want people to find it and see how easy it can be. Congratulations!
So sad to see a dead owl😢
Good day sir Tim 😊 Can I ask a question about determining the number of birds during sampling, like how would you determine that you are not counting the same bird since they tend to fly or move from one place to another without even noticing?
Great question! For something like the Breeding Bird Survey, it's actually pretty easy to keep track of different individuals because each count is only 3 minutes long. Plus, most birds are specifically singing on their territory during the season that we do the counts, so birds often sit tight during the count rather than fly all round. More generally, I think the answer is just that we are conservative in our counts. For example, imagine I hear one American Robin to my right that then goes silent. Then I hear an American Robin to my left. If I never hear the one to my right again during the count, I assume that I detected ONE individual that moved during the count. I wouldn't interpret this scenario as two robins unless I heard the birds to my right and my left at the same time.
Thanks for uploading this. While discussing this with my friend, he pointed out that instead of average, SUMPRODUCT involving the number of checklists in each week will be the right operation.
For sure, taking the average as I've illustrated is just one of many ways one could compile the data. There are also all kinds of data cleaning operations that would be important to do first before really digging into analysis.
hopefully this helps out with painting the barred owl in watercolor tomorrow night in class.
Well explained
Thanks for a great video. We found an owl skeleton and partial carcass on our property in Auburn, WA last month. We tried to key out the skull using a site, "Avian Osteology" from the Royal Museum in British Columbia. The "Barred Owl" and "Spotted Owl" skulls are very similar but we think it leans toward a "Spotted Owl" which would be extremely rare for our area. We are going to carefully check the feather patterns using your helpful video. Thanks for the great presentation.
Great video with good information! Thank you! 🦉
🇲🇨🇲🇨🇲🇨⛟⛟⛟🚛🚛🚚
It's sad to watch this dead bird.. Even tho we have learned more information it's still very sad and hard to watch this full grown bird just not moving.
What a beautiful little guy. Thanks for posting.
I think you just helped me with a major hurdle in my thesis, thank you so much!
Thanks a lot for sharing this on RUclips, it si really helpfull. Regards from Buenos Aires Argentina 🇦🇷❤️
Thanks for explaining this! Excel is my least favorite part of any study but it's so important nowadays, and you made this very simple and easy to understand. I wish you had been the one to teach my environmental statistics course!
guys this video isn’t disrespectful. it’s educational. he didn’t kill this animal nor would he want to.
how bout clean up your language...willnot watch any more of your videos
