| + | {{disambig}} |
| − | '''Alternative name: Blue-diademed Motmot''' | + | '''Blue-crowned Motmot''' may refer to one of six species previously considered conspecific under the name '''Blue-crowned Motmot''' (''Momotus momota''): |
| − | ;[[: Category:Momotus|Momotus]] momota
| |
| | | | |
| − | ==Identification==
| + | *'''[[Blue-capped Motmot]]''' - ''Momotus coeruliceps'' |
| − | 38-48 cm. Green upperparts (olive in subspecies ''osgoodi''), green or rufous underparts depending on subspecies (very variable how dark), black central spot on upper breast, black central crown surrounded by blue band (or crown entirely blue in subspecies ''coeruliceps''), black eyemask sometimes edged pale at the back. Tail is green with blue lower tail with two longest feathers showing an area missing barbs followed by an area with barbs (rackets); the tip of these feathers is black in some subspecies.
| + | *'''[[Lesson's Motmot]]''' - ''Momotus lessoni'' |
| − | | + | *'''[[Whooping Motmot]]''' - ''Momotus subrufescens'' |
| − | Notice that the tail feathers are normal when growing, the barbs fall off shortly after, and it is therefore possible to see a bird of this species that is missing rackets (feathers may also break below the rackets).
| + | *'''[[Trinidad Motmot]]''' - ''Momotus bahamensis'' |
| − | | + | *'''[[Amazonian Motmot]]''' - ''Momotus momota'' |
| − | Juvenile has reduced black on upper breast.
| + | *'''[[Andean Motmot]]''' - ''Momotus aequatorialis'' |

| − | ==Distribution==
| |
| − | [[Mexico]] to northern half of [[South America]].
| |
| − | | |
| − | ==Taxonomy==
| |
| − | Twenty subspecies are known for Blue-crowned Motmot. A recent paper<sup>[[#References|[2]]]</sup> proposes that these should be split into several species, here treated as groups:
| |
| − | *group ''coeruliceps'' from north-eastern Mexico is the only with blue crown; this is a monotypic form. Not included in the study mentioned.
| |
| − | *group ''lessoni'' from southern Mexico to western [[Panama]]. Includes subspecies ''goldmani'', ''exiguus'', and ''lessoni''. | |
| − | *group ''subrufescens'' from central Panama to north-central [[Venezuela]], with parts of [[Colombia]], in subspecies ''subrufescens'', ''osgoodi'', and ''spatha'', and isolated from the rest in south-east [[Ecuador]] and south-west [[Peru]] is subspecies ''argenticinctus'' (subspecies ''conexus'', ''reconditus'', and ''olivaresi'' no longer recognized). | |
| − | *group ''bahamensis'' from [[Trinidad]] and [[Tobago]] is monotypic | |
| − | *group ''momota'' from the Amazon bassin includes ''microstephanus'', ''momota'', ''ignobilis'', ''marcgravianus'', ''nattereri'', ''simplex'', ''pilcomajensis'', ''cametensis'', and ''paraensis''.
| |
| − | | |
| − | Notice there are differences between these groups and those listed in the Clements spreadsheet<sup>[[#References|[3]]]</sup>.
| |
| − | | |
| − | [[Highland Motmot]] has in the past been considered a part of Blue-crowned Motmot. | |

| |
| − | ==Habitat==
| |
| − | Habits near water, rivers, streams, and builds its nest in hollows excavated on banks. Likes to perch on branches in the shadow, inside forest.
| |
| − | ==Behaviour==
| |
| − | It nests in tunnels in a bank, 3-4 white eggs are laid.
| |
| − | | |
| − | The diet includes insects, lizards and fruit.
| |
| − | | |
| − | Most subspecies has a song consisting of two hoots, but the song is a single "whoop" in those belonging to group ''subrufescens''.
