Thanks for the pictures. They are great!
I did a little research and found the following interesting facts about Indigo Buntings at the Cornell Lab of Ornithology:
- The Indigo Bunting migrates at night, using the stars for guidance. It learns its orientation to the night sky from its experience as a young bird observing the stars.
- Experienced adult Indigo Buntings can return to their previous breeding sites when held captive during the winter and released far from their normal wintering area.
- The sequences of notes in Indigo Bunting songs are unique to local neighborhoods. Males a few hundred meters apart generally have different songs. Males on neighboring territories often have the same or nearly identical songs.
- Indigo and Lazuli buntings defend territories against each other in the western Great Plains where they occur together, share songs, and sometimes interbreed.
