Since the count for pelicans is so low, and pelicans are so large, I imagine at least one of the strikes caused a total write-off (i.e. crash) of a very expensive
plane.

Amazing how much damage some little Cliff Swallows can do! Also amazing how well
they can pin down the species of a bird after it collides with a plane.

I saw this item floating about and managed to download a copy from a google cache.

Basically, it purports to document the cost of wildlife strikes [by species] for the US Airforce, listed in total cost order [I don't know what the timescale for
this data set is].

Assuming the list has a factual basis, the pelican would be the most dangerous bird, with the average collision costing US$43 million, ten times the next most dangerous [griffons]. The most commonly struck bird is the 'horned lark', but
being a much smaller bird, the average cost is a mere US$2600 per strike.

Our friend the laughing gull appears to have been involved in a few prangs [43]
which cost an average of US$6300.

The humourous element in the list is the suggestion that pigs might fly ...
