Here's some bird ingestion data for you from the certification of a GE90 Engine (large commercial airliner engine)
"As part of the required certification testing, the GE90 successfully completed
both the 2.5 and 8 lb. (1.13 and 3.63 kg) bird ingestion tests on the engine’s
composite blades.
In October 94, four 2.5 lb. birds were ingested with the engine running at
speeds required to produce 85,000 lb. (377.8 kN) of thrust at takeoff on a hot
day. There was no thrust loss and the engine responded to all throttle
commands during the required 20 minutes of operation following the
ingestion."
