I do doubt there are 60 lbs geese flying around.
I remember the DC-3 used on the Fairford-Filton shuttle run in the early Concorde days (I flew on it).
That one 'collected' a 'mere' gull through the right windscreen.
F/O leant forward for an unknown reason... next moment there was this huge bang above his head, a shower of glass and feathers, and a big bloddy splash on the C/B panel behind him.
His time hadn't come yet.
