Flying Reptiles:
In JWE we did not have to worry about feeders in the aviairy, it was 'assumed' to be an auto replenish system as we could not send Rangers into them.
In JWE2 I'm hoping that will not be the case. As we currently know, Pteranodon is the only confirmed 'flyer' at this time. In JP/JW cannon they ate both fish, carion, and people.
For fish, I hope at the least, they skim the water, dip thier beaks and come up with a fish. I would love for them to dive from height, submerge, and come out with a fish. For carion, a carnivor feeder would suffice. I hope that they will buzz/peck at Ranger teams, if said teams can enter aviairy.
With the game's penchant for small/medium/large 'things', I expect to also have a large and small flyer. The large could do fish, carion, live bait, and small dinos. The small, I would love to see an insect feeder (dragon and butterflys).
I agree that we should be able to place viewing galleries at different heights. I also would like to choose my landing spots and choose different flight patterns from a list. The landing spost would be denoted by a 'bird's nest' in the size appropriate to the species size.
