Biomechanics illuminates form-function relationships in bird bills.
Krishnan A. Krishnan A. J Exp Biol. 2023 Apr 25;226(Suppl_1):jeb245171. doi: 10.1242/jeb.245171. Epub 2023 Mar 13. J Exp Biol. 2023. PMID: 36912385 Review.
The different shapes of the bill across bird species result in functional and mechanical trade-offs, thus representing a microcosm of many broader form-function questions. ...Following an examination of the interactions of bills with fluids and their role as part of the vo …

From snout to beak: the loss of teeth in birds.
Louchart A, Viriot L. Louchart A, et al. Trends Ecol Evol. 2011 Dec;26(12):663-73. doi: 10.1016/j.tree.2011.09.004. Epub 2011 Oct 4. Trends Ecol Evol. 2011. PMID: 21978465 Review.
Reviewing these lines of evidence, we propose hypotheses for its causes, with a prominent role for the horny beak during development. A horny beak and a muscular gizzard functionally 'replaced' dentition for food acquisition and processing, respectively. ...

The sensory world of the platypus.
Pettigrew JD, Manger PR, Fine SL. Pettigrew JD, et al. Philos Trans R Soc Lond B Biol Sci. 1998 Jul 29;353(1372):1199-210. doi: 10.1098/rstb.1998.0276. Philos Trans R Soc Lond B Biol Sci. 1998. PMID: 9720115 Free PMC article. Review.
A new hypothesis, along with supporting data, is presented for this combined mechanoreceptive-electroreceptive complex in platypus cortex. Bill mechanoreceptors are shown to be capable of detecting mechanical waves travelling through the water from moving prey. ...Combined …

A surrogate forelimb: Evolution, function and development of the avian cervical spine.
Marek RD. Marek RD. J Morphol. 2023 Oct;284(10):e21638. doi: 10.1002/jmor.21638. J Morphol. 2023. PMID: 37708511 Review.
The neck is a critical portion of the avian spine, one that works in tandem with the beak to act as a surrogate forelimb and allows birds to manipulate their surroundings despite the lack of a grasping capable hand. ...
