Aphelocoma ultramarina

Aphelocoma ultramarina

The Mexican jay is a medium-large (~120 g) passerine similar in size to most other jays, with a blue head, blue-gray mantle, blue wings and tail, and pale gray breast and underparts. The sexes are morphologically similar, and juveniles differ only in having less blue coloration and, in some populations, a pink/pale (instead of black) bill that progressively becomes more black with age (Brown and Horvath 1989). Some field guides misreport this color as yellow because the pale bill becomes yellow in museum study skins. The iris is brown and legs are black.
Mexican Jays range from the north in central Arizona, southwestern New Mexico and west-central Texas through the eastern central mountain chain south to Puebla, Guerrero and central Veracruz and went to Jalisco and Colima.

Kelp goose

Kelp goose The Kelp Goose is a striking species of coastal areas of southern Chile and Argentina.  They are strikingly sexually dimorphic - adult males are all white while females are fancier, with brown backs and white bars on black underparts and an iridescent green wing bar.  Both sexes show intensely yellow legs.  The species forages on kelp along rocky shores in pairs and rarely forms larger flocks like other species of South American sheldgeese.
