Heh... maybe they need to design for pigeon strikes and not chickens.
Really... when was the last time you saw a chicken in flight higher than
20 feet off the ground, or hanging around an airport?

Bird strikes happen near the ground as well as at altitude.

Pigeons and gulls on the other hand, or ducks... they get up there
a bit more. But are much smaller birds.

A structure that will take the impact of a larger bird will take a
smaller bird in stride.

How often do you strike 4 pounds of bird? Other than ducks and geese, I
can't
think of many 4 pound birds you might run a plane into.



Herring Gulls reach 1.5 kg

Cormorants have been known to be as heavy as 3 kg

Gannets are in the 2-3 kg range

Swans of various types can reach 10 kg

*On* the ground too, as illustrated by a pheasant and the right front
wheel of my car on sunday..

Um, there's lots... I've dodged plenty of hawks and buzzards- big ones over
5 foot wingspan too. It depends what area you fly in I guess.

Buzzards aren't God's smartest creatures either, they don't seem to yield to
anything no matter how big it is. (Even seagulls will give you right of way
if they see you in time.)

They may have the same logic of superior deterrent that seems inherent
to the limited brain of even a tame skunk.

Birds and Lieutenants scare me more than anything in the air...

I second Jim's words -- seems the MOAs and Restricted Areas have an
abundance of turkey buzzards and re-tailed hawks -- lethal-sized creatures
when they get in your way at high Q.

I've run into four birds in the course of my career, 3 daytime, 1 at night
(at 1500'AGL). Fortunately, they were the smaller varieties -- 2 starlings,
2 undetermined. One of the starlings punched a neat hole the size of my
fist in the leading edge of the intake, went through a couple vertical frame
members and lodged next to a fuel cell. Never knew anything happened 'til a
PC found it post flight in the fuel pits...Class C damage at the time.

AND if they are not so gorged on roadkill that they can take off.
I lost a radiator grille and a headlamp to a severely overloaded
seagull on the road near Lossie - its rate of climb was inches/hour.
As to lack of smarts - it was eating another seagull that had been
smooshed on the road earlier, it never entered its greedy little brain
to wonder how that meal had gotten there.

Seagulls and aircraft are an even worse mix.

Given such gross stupidity, can anyone explain why all gulls are protected
under current US law?

Pretty much. In fact, the size bird for the F-16 canopy tests was
upped from 'chicken' to 'turkey' after a collision with a California
condor.

You have to plan for the worst... Delhi is swarming with huge vultures.
Trust me, when one such is lurking on the branch of a nearby tree, one never
feels confident of completing tea on the terrace without incident. Not a 4 lb
bird.....

Yeah. I still recall the flight out of Dallas where we took a bird
strike to one of the engines by a turkey buzzard. Big and not very
smart.
