“…Expanding the knowledge on any avian lineage will be of value in resolving high-level patterns of the influence of diet and lifestyle on the gut microbiota. A lineage that we feel would be of great interest is the hummingbird, which possesses the fastest metabolism among homeothermic animals (Suarez, 1992 ) and relies on a diet primarily of nectar supplemented with arthropods (Brice, 1992 ; Yanega and Rhubega, 2004 ; Powers et al, 2010 ). As an adaptation to the extreme levels of sugar ingested, hummingbirds possess extremely potent sucrase (Martínez Del Rio, 1990 ) and are able to survive in a constant state of hyperglycemia (Beuchat and Chong, 1998 ).…”

“…In the breeding season, males may forgo defending the richest foraging patches and instead establish territories around resources that help procure mates, such as access to perch sites (Armstrong, ). Territories may also be based on the availability of arthropod prey (Stiles, ; Powers et al ., ) or the presence of insects that compete for nectar (Brown et al ., ; Gill et al ., ).…”

“…Additionally, Sandlin (2000) speculated that, within the same habitat, trapliners consumed more arthropods than territorial species. However, in a detailed study, Powers et al (2010) were not able to support this hypothesis by comparing the feeding ecology of the trapliner Eugenes fulgens and the territorial Lampornis clemenciae (both flycatching species) in southeastern Arizona.…”

“…Additionally, wing morphology also varies with elevation (Feinsinger et al 1979), feeding habit (hovering vs. perching), and male aggressive behaviour (Feinsinger and Chaplin 1975). Further, hummingbirds gain their energy mainly from nectar (Powers et al 2010) and only a small but variable amount from arthropods (see below). Therefore, it is more reasonable to assume that different factors, such as nectar-feeding ecology or habitatdetermined wing morphology, constrain both the way in which arthropods are caught and the different kinds involved.…”
