| new species of isospora from the blue-crowned motmot (momotus momota) from costa rica. | two (33.3%) of 6 blue-crowned motmots (momotus momota) sampled from costa rica were positive for a new species of isospora. oocysts of isospora momotana n. sp. have a double, thick, yellow to orange, 2.3 microm +/- 0.5 microm (2-3 microm) wall, contain 1 to 3 globular polar granules (1-4 microm), are ovoid with heavy pitting on the outer surface, and measure 29.4 +/- 2.3 x 27.5 +/- 2.3 (25-33 x 23-31) with an average length:width ratio of 1.1 (1.0-1.35). sporocysts are ovoid, contain a residuum ... | 2009 | 19469584 |
| air sac fluke circumvitellatrema momota in a captive blue-crowned motmot (momotus momota) in france. | postmortem examination of a 4-mo-old captive-born blue-crowned motmot (momotus momota) at the montpellier zoo in france revealed the presence of air sac flukes. circumvitellatrema momota (digenea: cyclocoelidae) was suspected and confirmed by molecular genetic analysis. digenean metacercariae were extracted from an invasive species of terrestrial snail, the conical periwinkle, subulina striatella. molecular genetic analysis determined that these metacercariae were also c. momota, confirming that ... | 2012 | 23082545 |

| morphofunctional study of the bill and hyoid apparatus of momotus momota (aves, coraciiformes, momotidae): implications for omnivorous feeding adaptation in motmots. | the present study contrasts available biological data and results of morphofunctional analyses of the bill and hyoid apparatus in motmots. it shows that these omnivorous birds, which take relatively large food items, possess osteomuscular peculiarities that enable them to process these items as a whole in order to soften or cut them, and make them suited for easy ingestion. for that, they use the crenate edges of their rhamphotheca. their jaws work as a highly mobile saw-like system. their mutua ... | 2004 | 15212364 |
