I was on a plane that ingested a bird. No damage to the engine, and it was a smaller (BAE) commuter jet. What was wierd is that the cabin filled with a smell like chicken fried in motor oil. I guess the cabin pressurization pumps run off the engines and the intakes are close enough to pick up that smell.
The cabin is pressurized with bleed air from the compressor section of the engine(s). So, the air intakes for the engines and the cabin air system are one and the same.
