Movements and Migration

Reports of the species from other habitats and areas are mostly likely to be misidentifications (13 Collar, N. J., L. P. Gonzaga, N. Krabbe, A. Madroño, L. G. Naranjo, T. A. Parker, and D. C. Wege (1992). Threatened Birds of the Americas. The ICBP/IUCN Red Data Book. Part 2. Third Edition. ICBP, Cambridge, UK. Close ), but some nomadism may have occurred in cases where nesting habitat was cleared and birds, unlimited by food availability, wandered in search of alternative areas to breed in (17 Roth, P. (1985). Notes on Spix’s Macaw and observations on some other bird species of northeastern Brazil. Report on the excursion in search of Spix’s Macaw, June 22 to July 24, 1985. Unpublished report.

Moreover, some wandering in response to rainfall appears to have taken place, with (e.g.) birds absent from their known breeding area from December 1986 to March 1987, reappearing when rains began (17 Roth, P. (1985). Notes on Spix’s Macaw and observations on some other bird species of northeastern Brazil. Report on the excursion in search of Spix’s Macaw, June 22 to July 24, 1985. Unpublished report.

The last wild bird sometimes disappeared for days or even weeks from its favored area.
