Genetic relatedness and morphology as drivers of interspecific dominance hierarchy in hummingbirds by Ubaldo Márquez-Luna, Carlos Lara, Pablo Corcuera, Pedro Luis Valverde

“…However, future studies should include (1) the temporal variability of the weight and (2) experimental predictor variables such the burst power of the hummingbirds to evaluate its effects on the dynamics of dominance hierarchies in hummingbird assemblages. …”

Self-adaptive Bioinspired Hummingbird-wing Stimulated Triboelectric Nanogenerators by Ahmed, Abdelsalam, Hassan, Islam, Song, Peiyi, Gamaleldin, Mohamed, Radhi, Ali, Panwar, Nishtha, Tjin, Swee Chuan, Desoky, Ahmed Y., Sinton, David, Yong, Ken-Tye, Zu, Jean

“…Bio-inspired technologies have remarkable potential for energy harvesting from clean and sustainable energy sources. Inspired by the hummingbird-wing structure, we propose a shape-adaptive, lightweight triboelectric nanogenerator (TENG) designed to exploit the unique flutter mechanics of the hummingbird for small-scale wind energy harvesting. …”

Areas of endemism of hummingbirds (Aves: Apodiformes: Trochilidae) in the Andean and Neotropical regions by Daiane Ouvernay, Ildemar Ferreira, Juan J. Morrone

“…ABSTRACT Using track analysis and cladistic biogeography, we identified areas of endemism of hummingbirds in the Andean and Neotropical regions. Our results point out that the current areas of endemism of hummingbirds occur in the Andes, Guiana Shield, the Lesser Antilles, western Central and North America and the Chiapas Highlands. …”

Floral phenology of an Andean bellflower and pollination by buff‐tailed sicklebill hummingbird by Mannfred M. A. Boehm, David Guevara‐Apaza, Jill E. Jankowski, Quentin C. B. Cronk

“…One diverse clade has evolved with extremely curved floral tubes and is predicted to be pollinated exclusively by one of two parapatric species of sicklebill hummingbirds (Eutoxeres). In this study, we focused on the floral biology of Centropogon granulosus, a bellflower thought to be specialized for pollination by Eutoxeres condamini, in a montane cloud forest site in southeastern Peru. …”

Vessel sound causes hearing loss for hummingbird bobtail squid (Euprymna berryi) by Rosalyn L. Putland, Rosalyn L. Putland, T. Aran Mooney, Allen F. Mensinger, Allen F. Mensinger

“…Yet, little is known about how invertebrates detect and respond to anthropogenic sound. The hummingbird bobtail squid (Euprymna berryi) has a short lifespan (&lt; 6 months), grows to sexual maturity around 90 days post hatching and its small size (&lt; 5 cm mantle length) makes the species an ideal candidate to examine potential effects of sound exposure under laboratory conditions. …”
