@Neotenico Год назад

I can't imagine the complex system of biological triggers and pathways required for an animal to REABSORB ITS ORGAN TISSUES. I'm curious if that process is exclusive to just the one subspecies or if it happens for all bar-tailed godwits before migration. Because that seems like it would be a pretty dramatic genetic difference, enough to classify as a separate species (especially in the ornithology field which, from what I've learned from my uncle's work, seems to be much more gene focused when it comes to taxonomy).

@ArawnOfAnnwn Год назад

Actually lots of animals have a similar capability, including us. It's a response to starvation. Even humans who're being starved will, in the later stages, begin to absorb their own tissues to survive. We can't do it at will, but this ability of theirs could have evolved from it.

@Neotenico Год назад

@@ArawnOfAnnwn The thing is, this is a seasonal trigger. When your body is starved of nutrients and starts consuming all the amino acids and triglycerides it can find, that's one thing. But to re-rig that biological response to a temporal (or temperature) factor is just nuts to me.

@clomiancalcifer Год назад

Tissue resorption isn't that weird for birds. Most for instance resorb a large part of their reproductive systems outside of breeding season. A lot of these triggers are hormone based, with the hormones themselves being triggered for production due to external stimuli. In many passerines (song birds) and some other migratory birds, this external stimuli is solar position and day length....usually in combination with some form of polarized light detection (in others it can be nutrient threshold loads). Solar position is of course fairly constant over millennia, and more reliable than meteorological data is for determining general 'good times for arrival'...typically. But then most bird populations' responsiveness to solar input is on a normal distribution or bell-shaped curve which means there's a breadth of reactions resulting in later and earlier arrival times, thus allowing for differential success and in theory species resilience should there be some kind of localized disentanglement of solar position and seasonal meteorology. That being said as climate starts becoming increasingly chaotic, we're seeing increasing failure rates of both migrations and breeding seasons as the classic entanglements of solar constants and meteorological response well...become disentangled more frequently. Survival is thus dependent on the depth or breadth of the behavioral 'background radiation' within the normal distribution of stimuli responses....which is more assured in cases of higher diversity and population size but is not guaranteed especially in populations that have very narrow margins for error, such as some of these long distance migrants banking on small, Arctic reproductive windows....

@NijosoSefzaps Год назад

@@Neotenico It's not actually that wild, if you think about genetics as a kind of "if...then..." series of statements. Which is an oversimplification, but changing from a starvation trigger to a seasonal trigger is a much easier feat than developing a new system from scratch.

@Neotenico Год назад

@@clomiancalcifer Sorry to reply so late, but wow. Thank you for such an in-depth response and tremendous amount of information. I was unaware that avian evolution was so deeply tied to solar position. Considering the most stable system on our planet is its own orbit, I'm kind of embarrassed I couldn't deduce that it would be such a powerful driving force for adaptation. Your comments on climate change, its role in desynchronizing the solar/meteorological status quo, and the subsequent impact on species that depend upon that status quo for biological triggers makes a lot of sense as well. Yet another example of the unfortunate fragility of evolutionary specialists.

@krisjonesuk Год назад

I live close to an estuary on the east coast of England. We get many Bar-tailed Godwits on the river here from October till early April. Once they develop their summer plumage they migrate. A local ornithologist recently identified one that had been ringed in Iceland 19 years ago!

@johndavey9129 Год назад

Australia is a destination - not an emergency landing if blown off course from New Zealnad. Last week a Bar-tailed Godwit was identified having flown from Alaska to Tasmania - a world record distance of 13,560 klms. I live on Lake Illawarra - approx 100klms on the coast south of Sydney and I spotted my first Godwit for the summer season a fortnight ago. Otherwise - loved you post.

@fubberpish3614 Год назад

I believe it's a different subspecies that regularly migrates to Australia, rather than baueri that usually heads to New Zealand.

@sukeshkohli475 Год назад

Incredible long flight maiden journey of 13,560 Kms made by 5 months old juvenile bird. GOD is so great, when you look at these incredible birds making an impossible non-stop journey flying across the pacific non-stop day and night without navigation. Beautiful GOD and it’s creatures❤

@anarchyantz1564 Год назад

Would like to know from an evolution perspective how they all "decided" to fly such a large distance and when there why not stay there?

@clomiancalcifer Год назад

Well decision is the wrong word. It was likely a gradual process of divergence between flight pathway populations, that expanded as populations optimized reproduction with risk. Arctic summers represent excessively long days, limited predators, fewer competitors, not nearly as many parasites and copious amounts of food. They don't stay there for obvious reasons that winters are harsh to say the least. Temperate and tropical environments have of food, yes but not as densely packed as the Arctic summer, have more acceptable climates year round, but do not have have the 24 hours of sunlight that the Arctic has, and also have lots more predators, competition and parasites. Whilst travelling is risky, the rewards for getting travel right are great, and whilst the rewards for staying temperate or tropical are...limited and the risk is as great or riskier, especially since many tropical and temperate niches are already quite heavily satiated...thus forcing many species into more extreme strategies to find adequate resources for reproductive success.

I may have encountered a Bar-tailed Godwit blown off course. Two weeks ago, found a dead bird in my backyard. He was a multi-brown color and had a strange long beak, not common to birds in my area, which is Milwaukee, Wisconsin. I've taken pictures of him/her and plan to ask the local DNR about identification. Right now I can say it looks exactly like some of the birds pictured in this video.
