Most birds above a 1/2 kilo will do plenty of local damage to most aircraft structures (except windscreen} at 300 kts or higher (at the min expect at least a hole) between 250 and 300 kts expect a big dent as min damage.
The engines won't much care as long as they are at climb power or more, but if at reduced power for approach they may have substantially increased the chance of damage downstream of the fan.
