Restlessness in birds, known as "zugunruhe", describes anxious behavior in migratory animals, especially in birds during the normal migration period. Sandhill (and Whooping) Cranes tend to show obvious signs of this in the fall as they dance around and pick up and play with sticks. Very informative. Thanks, guys!
Interesting, I have seen a golden eagle in migration carrying a big stick....obviously not about to build a nest in the fall, and they don't breed in this area anyway
You brought up a good point about birds that are more strict on their diets, such as insectivores and ones that will also eat fruits, nectar, buds, and certain berries. One short to medium-distance migratory bird found almost worldwide that seems to be more sensitive to colder temperatures is the Osprey. Larger rivers that don't ice up, along with warm winters that keep lakes and ponds open, can still supply Ospreys with food. But they still decide to leave. We've had occasional Snowy Owl sightings along the shoreline during the winter here in CT. One bird that's chiefly an insectivore and used to be a short distance migratory species here in CT has become a common year-round resident. That's the Carolina Wren. The abundance of vines and decorative trees and bushes that produce berries have made the American Robin not as migratory as it used to be. Northern Mockingbirds can sometimes be found in the same type of environments during the winter.
I truly admire (and enjoy) the wide range of bird related topics you two are increasingly addressing. The more theoretical the subject, the more engaging the ensuing commentary discourse. That’s great. “Come for the video; stay for the discussion!”. That could be your 2025 byline. 😊
Day length is more than a cue for migration. At high latitudes it’s a multiplier of resources. Tropical days are about 12 hours year round, but at the Arctic Circle days are 24 hours in mid June and zero hours in mid December. A bird that can forage 20 hours a day instead of 12 can produce eggs quicker & have a larger clutch, then feed those young and get them fledged quicker, minimizing vulnerability in the nest. Day length is the key that makes the effort & danger worthwhile - on average in terms of reproductive success versus dying en route - of migrating and setting up territories at both ends. And day length a reason to leave high latitudes. A bird needs to move far enough south in the autumn that it can find enough food during the day at that new latitude to keep it warm enough.
I read somewhere a long time ago that birds might also see changes in the plants around them, differently than we humans do. I don't know if that has been proven or even investigated much, but if birds see a slightly different spectrum from us, then the leaves of deciduous trees probably would look different to them, and maybe they really would see the initial changes as the leaves get ready to turn but haven't actually changed color (to human sight) yet. I've also seen a lot of research that indicates the hours of sunlight might be a big factor, but the possible impacts of temperature-as-migration-signal is a big focus of research right NOW because of the climate crisis. I think they discussed certain crane species (this would've been over on the channel SciShow and it wasn't recent either), basically scientists trying to figure out IF the fact that winter starts later and later in some places is affecting the cranes and their migration patterns. As complicated as birds are, it makes sense that there'd be many different factors and signals to get them moving when it's time. But we ALSO know that birds are super adaptable, so they might adjust without any human intervention!
It’s funny because scientists in reality know very little about birds in general and even less about specific species. It seems highly speculative vs concrete at this point
@@BadgerlandBirding You're very right! Though I imagine it IS hard to research creatures that literally fly away on you, hehe I remember reading about the folks tracking the Godwits (a group in New Zealand) and how incredibly hard it was to tag even a few of them. And we can only learn so much from observation, too. But THAT means: we have lots to look forward to learning!
Good morning to you from Hong Kong 🇭🇰 SAR. About a year and a half ago, I spotted a Yellow Bittern two times, right out in the open near the much wooded area along the beachfront promenade in the New Territories of Hong Kong 🇭🇰 SAR. TYE Yellow Bittern is if the Old World origin, breeding in the northern Indian 🇮🇳 Subcontinent, east to Russia Far East, Japan 🇯🇵 and Indonesia 🇮🇩. It’s mainly resident, but some northern birds migrate short distances. Since those two last sightings, I have never seen them again.
Thank you for this wonderful video. Such a tremendous selection of birds to view. Thank you so much for sharing. I will view the video you recommended. Hope y'all had a Happy Christmas and have a safe Happy New Year.🕊
I really enjoyed this one! Thanks for sharing your expertise. I live in OH. Robins stay year round. For me, the sign of spring is red winged blackbirds. I think our milder winters are keeping some species here longer. I noticed a kingfisher the other day that would normally be gone by now. I love these types of teaching videos. Thanks!
i have a question please. I was given a used pair binoculars from my neighbor a few days ago. i never had any binoculars. they look in very good condition. i live in a residential area of Chicago. Will a pair of Nikon Nippon 9x35 binoculars work for birding? i didn't ask what he used them for. and i see no birds outside now. Thanks
@BruteForce. Nikon is great! I think those should work fine, especially if you’re just backyard birding. I would check out this video th-cam.com/video/0VTgKeLtXM8/w-d-xo.htmlsi=_p0YULi62s1C1Uo-

It seems Carolina Wrens and Mockingbirds are moving north in general! They’ve become a lot more regular in the Midwest.
@@BadgerlandBirding Another one is the Red-bellied Woodpecker. They've become more year-round and are moving north like the Carolina Wren.

Another cool, informative video -- thank you for cranking out so much content. You are a couple of machines.
Appreciate the compliment! We love to make content!

it amazes me that these little birds fly such vast distances. i can barely get to the fridge. lol jk Thanks for sharing.
lol 🤣 thanks for watching!
