Very birb

I like its bristly look.

"crows" and "ravens" are needlessly capitalized.
"it's ancestor" should be "its ancestor".
There should be a space between "biomes" and "Like their ancestor".
"made for" suggests these were manufactured; I suggest "suited for".
"peg like" should be "peg-like".
"Earths insectivore" should be "Earth's insectivore".
"Normally solitary they" there should be a comma after "normally solitary".
"predators kills carrion". Did you mean, "other predators' kills" or "carrion resulting from other predators' kills".
"rather quickly" should be a comma after it.
"way of predators" should have a comma after it.
"with with" is a repetition error.

This guy’s ancestor is now in the genus Maineidrakon, as such this guy should also be included in the genus unless you plan on making it distinct.

Do they mainly flap or do they soar when they can? I feel like that would b an important detail to tell whether these are more comparable to crows or ravens.

Fixed the errors.
