Don't think of suggesting load cells.
But probably a bit out of the price range for this sort of project.

Last time I used them was for under road weighing of trucks.

sparkfun sells a very cheap one for $50 but its rated up to 50kg


Another way would be a couple of accelerometers and measure the force 
from the birds landing. Might have difficulty with small finches but 
should work for Bob's vultures.
