I also think in addition to the bearyena hybrids that they should add Blue Bird or Birds of Prey hybrid genes. To tame a blue bird they should add special trees where adult bluebirds build their nest. Only creatures with double wings should be able to reach these nest. If the bluebird who built the nest there is still alive there should be eggs in the nest, but if it is killed the eggs should hatch and turn into hatchlings. They should work like the bearyena babies and need 3 food to tame but the will always follow who tamed them. After they are fully grown female creatures should be able to mate with them. I think the new genetics they should bring are BlueBird Beak, BlueBird Wings, BlueBird Hindlegs (Look like Talons), BlueBird Body (coved in Blue Feathers), and BlueBird Tail. The affects and stats I think should be on these will be listed bellow.
BlueBird Gene Stats
BlueBird Beak: 2 strength 2 fishing
BlueBird Wings: 4 in flying if creature has double wings creature can have 1 BlueBird Wing and 1 wing and can still fly normally)
BlueBird Hindlegs/Talons : 2 carrying 1 fishing 1 strength
BlueBird Body: 2 sentless 2 cold resistance
BlueBird Tail: 2 heat resistance
New Abilities
Carrying: Allows creatures with a 1 in carrying to carry krabbits, baby nichelings ( I think that is how it is spelled), baby bearyenas, baby BlueBirds, and rabbits. Creatures with a two in carrying can carry all age of nichelings everything a 1 in carrying can carry, teenage bearyenas, teenage BlueBirds, Clownkoi, and the Piranha thing. When one of these creatures are being carried the nicheling carring them can drop them off in any tile in range or keep carring them where ever they please. This will make traveling to ports quicker and running away from those annoying apes easier.
