I generally put family tree "stuff" in the applicable threads - i.e., Trey's tree is under Radisson Peregrines etc.
As for using icons and sighting information, that's a winter project I'm afraid. I am working on family trees for all our birds in a format that is easy to update as new information comes in and which is easy to understand - either graphically and/or textually. Since we have over 200 birds released here in Manitoba and there is no central registry for the chicks produced away by Manitoba peregrines, it takes more than a little work to track down who, what, where and from whom - but I'm working on it ...
At the moment, Manitoba peregrines nesting elsewhere are included under Manitoba Peregrines - for example, Radisson in Edmonton is under Manitoba Peregrines instead of with the rest of the Alberta peregrines under Canadian Peregrines. I try to include background on the birds and their offspring in each board.
At the moment, that's all I can provide, only so many hours in the day I'm afraid ...
