As it appears you main requirement was to achieve a large DOF I would have set up in Aperture Priority probaly around f8. I'm basing this on the assumption that a too shallow DOF would have not given an end result you would have wanted.
I would have then taken a number of shots at varying ISO and Speeds and kept my fingers crossed that no blury birds ruined them.
Due to the time available I would also have used Auto ISO so that all I had to do was adjusyt my speed.
If I had been lucky with this method I may have ended up with similar to what you have posted.
PS. Humours in the last line !
