“…It is unlikely that UV reflectance plays a major role in red-breasted sapsucker plumage or signalling (Eaton & Lanyon 2003), however, UV coloration may require consideration when imitating some species. Hard decoy materials have the capacity to injure the bills of birds in the course of their provoked aggression (Slevin et al 2016), though this is of minimal concern for the robust bills of woodpeckers. While the hardness of many solid plastics is comparable to that of the injurious wooden decoys (Slevin et al 2016), 3D-printed plastic hardness can be functionally reduced through design (Böğrekci et al 2019).…”

“…Even with targeted mist-netting, it can be challenging to capture a particular species of interest. In effort to improve capture rates, decoys made from taxidermied conspecifics are deployed near mist nets to lure territorial birds closer (Angelier et al 2010; Slevin et al 2016). Despite their efficacy, good decoys can be difficult to source.…”

“…Despite their efficacy, good decoys can be difficult to source. Carved wood, stuffed fabric, papier mache, and sculpted clay decoys (Slevin et al 2016; Heward et al 2017; de Zwaan et al 2021) are sometimes used, but require artistic skill to render a lifelike replica capable of attracting a bird. This may be beyond the talents of many biologists.…”

“…This may be beyond the talents of many biologists. These decoys are often fragile, susceptible to water damage, and may pose a risk of injury to particularly aggressive birds (Slevin et al 2016). Some decoys are available for purchase, but these are often limited in species.…”

3D-printed decoys are as effective as taxidermied decoys in attracting red-breasted sapsuckers for mist-netting

Decoys often improve targeted mist-netting efforts by drawing the species of interest to a specific area nearer the net. Traditional decoy constructions include taxidermied carcasses, hand-made wood or clay figures, or professionally made products purchased from companies that provide a limited number of species, sizes, shapes, and markings. 3D-printing allows ornithologists to customize decoys to their own study species' specifications using cheap, durable, and replaceable materials. We show that red-breasted sapsuckers (Sphyrapicus ruber ruber) respond with equivocal aggression towards 3D-printed decoys and taxidermied decoys, demonstrating 3D-printed decoys as an effective tool in attracting birds towards a mist net for capture.

“…Although there is no previous evidence of infanticide by Prothonotary Warblers, they can be quite violent; we have observed physical confrontations that include violent pecking of heads (Slevin et al . ) and have documented injuries to adult birds such as a sunken eye of a female (T. J. Boves, A. E. Matthews, and M. C. Slevin, unpubl. data).…”

Female song in passerine birds may be more common than traditionally assumed, but it is not well‐documented or understood, especially in migratory species. We describe the first evidence of sex‐specific songs produced by female Prothonotary Warblers, as well as the results of playback trials aimed at exploring the adaptive function (if any) of this female‐specific vocalization. Based on the behaviour of three females and our playback trials, we suggest that these unique songs are related to mate acquisition during the early stages of courtship.

Performance of wild animals with “broken” traits: Movement patterns in nature of moose with leg injuries

Organismal traits are presumed to be well suited for performance in the tasks required for survival, growth, and reproduction. Major injuries to such traits should therefore compromise performance and prevent success in the natural world; yet some injured animals can survive for long periods of time and contribute to future generations. We here examine 3 years of camera trap observations along a remote trail through old‐growth forest in northern British Columbia, Canada. The most common observations were of moose (2966), wolves (476), and brown bears (224). The moose overwhelmingly moved in one direction along the trail in the late fall and early winter and in the other direction in the spring. This movement was clustered/contagious, with days on which many moose traveled often being interspersed with days on which few moose traveled. On the video recordings, we identified 12 injured moose, representing 1.4% of all moose observations. Seven injuries were to the carpus, three were to the antebrachium, and two were to the tarsus—and they are hypothesized to reflect damage to ligaments, tendons, and perhaps bones. The injured moose were limping in all cases, sometimes severely; and yet they did not differ noticeably from uninjured moose in the direction, date, contagiousness, or speed of movement along the trail. We discuss the potential relevance of these findings for the action of natural selection in the evolution of organismal traits important for performance.
