"I did it on a lark"
"Don't pigeonhole me"
"I'm gonna go out on a limb here and say..."
"That dovetails nicely..."
"That's hard to swallow"
"This is our swan song"
"Canary in the mineshaft"
"Kill two birds with one stone"
"A bird in hand is worth two in the bush"
"I'm really winging it with this one"
"What's sauce for the goose is sauce for the gander"
"Blue-footed booby"
"Duck!"
"Eagle eye"
"Hawking my wares"
"Feeling a bit peckish..."
"Coming home to roost"
"Don't put your eggs in the same basket"
"Cook your goose"
