What animals were associated with the sun in Mesoamerican culture?

The two most directly associated would be the eagle and the jaguar - both of which leapt into the great fire to give birth to the Fifth and present Sun, according to Aztec mythology. It seems that the jaguar appears first in terms of the earliest clear representations of the sun (god), in a depiction of the Maya kin sign for sun/day, in present-day Belize, and also in Central Mexico.
Other creatures had solar connections too, however:-
• The deer can be seen carrying the sun opposite a rabbit carrying the moon in the Codex Borgia (see pic 1) - according to Alfredo López Austin the idea of rain falling and the sun appearing at the same time evokes an ancient concept of a doe (female deer) giving birth in northern Mexico
• The hummingbird also has connections to the sun, in part through the solar deity Huitzilopochtli (‘Left-handed Hummingbird’) (follow the link below on special birds).
• Finally, we think the (scarlet) macaw with its fiery colours may have been the ‘companion spirit’ of the sun, just as it is for the Pueblo people of the Southwestern USA.
