Do Hummingbirds Hum?
Hummingbirds may be the smallest birds in the world, but they have the biggest appetites. Their wings flutter on average fifty to eighty times each second as they visit hundreds of flowers over the course of a day to sip the sweet nectar that sustains them. Their hearts beat nearly twelve hundred times a minute and their rapid breathing allows these amazing birds to sustain their unique manner of flight. They can hover in the air for prolonged periods, fly backwards using forceful wings that swivel at the shoulder, and dive at nearly two hundred miles per hour. Native only to the Americas, some hummingbirds have been known to migrate from Mexico to Alaska in the course of a season. Watching a hummingbird at a backyard feeder, we only see its glittering iridescent plumage and its long, narrow beak; its rapidly moving wings are a blur to our eyes.These tiny, colorful birds have long fascinated birders, amateur naturalists, and gardeners. But, do they really hum?InDo Hummingbirds Hum?George C. West, who has studied and banded over 13,500 hummingbirds in Arizona, and Carol A. Butler provide an overview of hummingbird biology for the general reader, and more detailed discussions of their morphology and behavior for those who want to fly beyond the basics. Enriched with beautiful and rare photography, including a section in vivid color, this engaging question and answer guide offers readers a wide range of information about these glorious pollinators as well as tips for attracting, photographing, and observing hummingbirds in the wild or in captivity.

Robo de néctar en Campsidium valdivianum: observaciones sobre la morfología floral y el papel de abejorros y aves en el sur de Chile
En los bosques templados de Chile y Argentina, muchas plantas son polinizadas por el colibrí Sephanoides sephaniodes. Una de ellas es la enredadera Campsidium valdivianum. En Argentina, el abejorro nativo Bombus dahlbomii roba néctar de las flores de C. valdivianum, mostrando preferencia por aquellas con corolas más largas. En Chile, las flores de C. valdivianum presentan tanto perforaciones pequeñas como grandes, lo que sugiere una mayor diversidad de ladrones de néctar. En el área de estudio, el robo de néctar podría ser atribuido a abejorros nativos y exóticos (B. dahlbomii y Bombus terrestris), que serían los responsables de las perforaciones pequeñas, mientras que las aves nativas (Phrygilus patagonicus y Elaenia albiceps) serían las responsables de las perforaciones grandes. Planteamos la hipótesis de que las plantas con flores más largas y estrechas experimentarían un mayor robo de néctar, tanto por abejorros como por aves, en comparación con aquellas con flores más cortas y anchas. Evaluamos los efectos de la longitud, el ancho y la variabilidad de la corola entre plantas individuales sobre la incidencia de perforaciones pequeñas y grandes. Encontramos que el 6.7% de las flores presentaron perforaciones pequeñas, mientras que el 14.8% mostraron perforaciones grandes. La longitud de la corola no se correlacionó significativamente con la ocurrencia de ninguno de los dos tipos de perforaciones. No obstante, las aves parecieron diferenciar entre plantas individuales en función de factores no considerados en este estudio. Comprender la frecuencia y las causas del robo de néctar resulta esencial para avanzar en el conocimiento de la ecología y la evolución de los rasgos florales de las plantas polinizadas por colibríes en los bosques templados de América del Sur.
