Oven Ready,
The reward system in use demands Eduardo fly to get his eats. He is starting to learn that cheating by making multiple short flights or walking does not get him anything. He is also insisting on bigger rewards. Holding feed container gets him going when sight of single mealworm does not.
I am banking that on a open short grass football field he is going to feel vulnerable and might even commit to flight just to reach cover. This based in part on my inability to walk a flock across an open field. When I attempt to walk them across field, they either cut back into fence row behind me or flush into flight across field to next available cover (fence row or building).
During winter with birds in woodlot, my birds if pushed / flushed would also power flight up through trees (> 80 feet) and transition to horizontal flight back to barn which was almost always not in line-of-sight making any accurate estimates on actual distance covered and time difficult. It takes them a couple hundred feet horizontal distance to get above trees but from my perspective it looked almost vertical.
Estimating flight speed will require distance and time for me. Part of reason for using football field since it has marks. Based on experience with these guys when I was a kid, trimmed out flight speed is in range of 25 to 40 miles per hour. Cross winds likely pushed for higher end of that range. Stall speed is at lower end of range. I might be able to borrow radar from campus police (office is next to football field).
"Startler" in end will be used to get really long flights which should be much better than voluntary performances. Startler must not be recognizable as being me. Also do not want to get in trouble with causing undo stress on Eduardo in eyes of some observers. I will be doing some of this in a very public setting. Startler will be addressed later. Got any ideas on how it would look / work? Giant owl face?
Flight weight is an issue here. Best flying birds I had as kid possessed muscle bound breast and abdomen was firm and tight. Mentallity of Eduardo may also be like that of a hawk trained for falconry, a little lean makes for more effort on the wing.
