>>Bird call training / voice training. Met a decent amount of birds who trained themselves to be able to do calls. A syrinx gives a tone that's alas hard to copy with a larynx, but being able to reproduce bird calls through wistling or other methods is common! <<

While I am not a bird myself, I am a shapeshifter. I like doing bird calls and am good enough with a few to get answers.

>> Still personally perfecting my ability to beak-clack ahah, that one has been tricky.<<

Try the Xhosa clicks.

>>I personally pursue entomology partially because, well, i've got a predatory instinct toward insects and just enjoy catching and id-ing them due to this. <<

I've got the hunter-sight that breaks camouflage and locks onto motion. It works with insects among other things, and for birdwatching.

>>Gender. This one is kinda external and internal. I don't tend to really... tell people i'm a bright. But i act like a bright. <<

What a great way to put it!

>> Building a life around instincts, instead of restricting instincts for human life. This is also complex. By default, human society is not accomodating to nonhuman instincts. Making nonhuman instincts a priority over deffering to human rules is hard. However, it is possible.<<

True -- and for some people, it's necessary, because they just can't fake being human well. At maximum effort, I can manage about 3 hours, then the rest of me spills out. I rarely bother to conceal it.

>> I know at least one migratory bird who actively migrates, changing continents from summer to winter, and who is building a life around this cycle. <<

Here in central Illinois, many ordinary humans are migratory! The farmers have winter homes in Florida. In fall, they race to see who can finish harvesting first and fly south. Really. Some jobs are also migratory, like beekeepers who deliver rental hives to orchards, they have to follow the flowering season. So for a migratory bird person, I would recommend looking for a community that considers migration normal. It's one less stress.
