   I’d guess the odd one out (the pale blue) is the Brown-Headed Cowbird egg.

   The blue one is the Song Sparrow egg and the rest are Cowbirds and, as a native species, the Brown-headed Cowbird is protected under the Migratory Bird Treaty Act, and taking eggs is illegal. So any person who violates the Migratory Bird Treaty Act by murdering baby cowbirds is subject to a criminal penalty of up to $5,000 for each bird unlawfully taken, killed, harassed, or possessed; civil restitution fee for each bird unlawfully taken or possessed; and a license suspension or revocation
