Aug 15, 2023 at 12:23 comment added John @LioElbammalf so you don't understand how leverage works. You should really look at studies on flight mechanics, lots of bords with large heads and long necks fly with the neck fully extended and just extend their legs behind them. bird often have the opposite problem being too tail heavy because of how much of the body is behind the shoulder joint. You are claiming this will somehow prevent economical flight when its just not a large issue. ecoevocommunity.nature.com/posts/to-be-stable-or-not-to-be
Aug 15, 2023 at 10:45 comment added Lio Elbammalf @John Unless that neck puts the head so far back it sits above the wings you'll still want something to counter it.
Aug 15, 2023 at 1:59 comment added John @LioElbammalf or a S shaped neck which is how pterosaurs and birds and even bipedal dinosaurs do it.
Aug 14, 2023 at 21:44 comment added Lio Elbammalf @John "Positioned for balance" is precisely the point of what my comment was saying. A heavier head needs a counter balance somewhere to be positioned for balance.
Aug 14, 2023 at 20:56 comment added John @LioElbammalf except that's not how flight works, once the head is positioned for balance no extra effort is needed. height is not an issue for birds they don't breath the same way we do, a bird at 10000ft can breath just fine
Aug 14, 2023 at 20:09 comment added Lio Elbammalf @John Whether that is true or not, the logic still stands. If you have a front heavy bird it'll have to put extra effort into stopping itself from tumbling and is unlikely to reach the desired peregrine falcon heights.
Aug 14, 2023 at 0:06 comment added John @LioElbammalf except the largest animal to ever fly had an absolutely massive head and no tail to speak of, and lots of birds have huge heads.

Feb 6, 2017 at 16:25 comment added user There is no meaningful evolutionary distinction between "Earth's 18th century" and "present-day Earth", unless of course you mean the 18th century after the formation of Earth, at which point almost no matter which definition of "formation" you use you are looking at a dead, molten ball of lava.

Feb 6, 2017 at 11:40 comment added Lio Elbammalf I think the main restriction you'll be fighting is balance. Most birds have small heads - less weight at the front and their centre of mass is very...central. Teeth need strong jaws, jaws need muscles. All this mass you put towards the head the more mass you need to pile on the tail end (or longer tail) in order to balance yourself about the wings so your "bird" can put more effort into flying and less into stopping itself from tumbling.
