As i wrote this i might have figured an partal answer...brb checking... ok nope changing to ignore whisle didn't make it ignore the perch...
(i really hope i don't have to use the NAMING option is so can you add a exception filter?)

I think is is kind of simple i want my breeding birds NOT to try to get to a perch.

also it might be nice'ish if i could set a group of perchs for call group 1.

i have over 40 Dimorphodon that i use as an attack group.. over kill yes but it's so much fun to watch them eat a Bronto.

the perches work amazing it takes about 2 min's for them all to land but they do in nice lines i have two rows of small perches end 2 end.. so i can just move down the line checking stats/empty eventory.. what ever i need.. i used to have to sit at the beach and pick them up and put them all in a row... or check each one then pick it up and toss it in the done pile...

another wish would be to link perches so i can change the settings in the linked group...

amazing mod thank's for all the time and work you've put into it.
