WIYM: Spell the Word B-I-R-D in Postcards

Spell the word B-I-R-D with the pictures of a postcard. The catch is: one of the postcards must be a bird postcard.

Example:
B - Bird, Bridge, Bear, etc
I - Indigo Bunting (bird), Illinois, Island, etc.
R - Rooster (bird), Recipe, River, etc.
D - Duck (bird), Did You Know, Denver, etc.

Send the 4 blank postcards in an envelope. Postcards should be unwritten and unstamped. They should be store bought only and of good quality. (No handmade/freebie/ad/zazzle). Let your partner know which postcard represents which letter. Remember, one of the postcards must be of a bird.
