2011), we know only one other example where a white patch has been shown to be indicative of resistance against chewing lice, namely the wing bars in house sparrow (Passer domesticus). There are chestnut brown patches on side of the head below the eye. Hello, I met some sparrow-looking? The Abd al Kuri Sparrow is sometimes considered to be a subspecies of the. We investigated whether differences between males in any measured trait, apart from manipulated wing bar, affected female decision. Effects of uropygial oil on feather-degrading bacteria, Effects of light environment on color communication, Depigmented wing patch size is a condition-dependent indicator of viability in male collared flycatchers, Within-male melanin-based plumage and bill elaboration in male house sparrows, Haste makes waste: accelerated molt adversely affects the expression of melanin-based and depigmented plumage ornaments in house sparrows, Elaborate ornaments are costly to maintain: evidence for high maintenance handicaps, © The Author 2011. 1999). We recorded whether females were resting, eating, drinking, moving, or showing interest for any male (paying attention to the male and standing close to him) and recorded their position (left or right side or in the center of the cage). The male Sind Sparrow has gray crown; chestnut stripe running down its head behind the eye; black throat patch. The closest relative to Spanish Sparrow is the House Sparrow. 2007; also see Gustafsson et al. Controlling for differences in tarsus length between control and experimental males, we found a significant difference in rating of experimental and control males, with females preferring control males (RM-ANOVA; treatment effect: F1,14 = 10.01; P < 0.01; treatment × difference in tarsus length: F1,14 = 12.85; P < 0.01; Figure 4). Means are given with the standard error. (Feather wear or lighting could cause the bird to look like it has a wing bar.) Males were matched for their wing-bar size, which was measured by means of photography on gridded paper with a digital camera (Nikon Coolpix 4300; following Figuerola and Senar 2000). Therefore, we repeated the analyses weighing by the whole rating value (as indicative of motivation) of females. For this reason, it has usually been considered that there is no cost of development for plumage with this color. Nevertheless, females also preferred males with less feather holes caused by chewing lice and larger males. Inés Álvarez, Carlos Castillo, Antonio López, and Maribel P. Moreno contributed to the care of the animals. In fact, at least 2 studies have shown that individuals with more extensive white plumage have larger uropygial glands, in the barn owl (Tyto alba; Roulin 2007) and with respect to the wing bar in the house sparrow (Moreno-Rueda 2010). By mating with more ornamented males, females may choose less parasitized partners, and benefit by reducing the probability of contagion of parasites with direct transmission. The crown is gray and chestnut extends from behind the eye to the nape and back. From genes to populations, Multiple cues in status signalling: the role of wingbars in aggressive interactions of male house sparrows, Risk-taking and survival in the House Sparrow. White-crowned Sparrow. One researcher (G.M.-R) recorded the behavior of females, by scans at intervals of 1 min for 1 h, from a hiding place 15 m from the cage. Parasites, by extracting resources from their hosts, decrease the host’s fitness, becoming a strong evolutionary force for hosts (Gómez et al. "sparrow" with parallel white wing bar - south Poland. Given that males with larger uropygial gland show larger wing bars, by choosing males with larger wing bars, females appear to be concomitantly choosing males with larger uropygial glands, and thus, higher resistance against chewing lice (Moreno-Rueda 2010). During the experiment, weather was constant, consistently sunny, with no rain or wind. Therefore, wing-bar size offers information concerning resistance against chewing lice and could be used by females in mate choice. Bib and wing-bar color are not significantly correlated (Václav 2006), suggesting that these 2 sexually selected traits signal different aspects of the phenotype of the house sparrows. Oxford University Press is a department of the University of Oxford. The Parrot-billed Sparrow is considererd by some to be a subspecies of the Northern Grey-headed Sparrow. The standard error is in brackets. The. Male Chaffinch The adult male is slightly larger than the female and has a black forehead, blue-grey crown and nape; rich pinkish-brown face and under parts, fading to white … In the other male (control male), we painted with the black marker a similar portion of the brown covert feathers closest to the wing bar, therefore showing coloration similar to that in experimental males (measured with a spectrophotometer Konica Minolta CM-2600d). Note the stripes on the head and gray throat. Wings have small patches of yellow and two white wing-bars. Bib size may signal dominance (Anderson 2006), whereas wing bar signals resistance against chewing lice (this study). 2003; Hanssen et al. For 24 h, 16 different females were placed in an experimental cage of 50 × 35 × 35 cm. A two-sample proportions test revealed significant differences in preference for experimental and control males (z = 2.48; P = 0.01). The Eurasian Tree Sparrow has chestnut crown;, nape; white cheeks with blaqck patch. The camera was mounted on a tripod, consistently at the same distance from birds. And recent results suggest that sparrows with larger uropygial glands, and thus with fewer feather holes, molt slower (Moreno-Rueda, submitted), thereby allowing them to develop a larger and whiter wing bar (Vágási et al. If you think the sparrow in question has a wing bar but the descriptions of the birds under this category clearly do not fit, then move down to the “Faint or No Wing Bar” list of birds and try again. Female has streaked brown back; grayish head; pale supercilium; buff-white underparts; small bill. I: mechanisms and measurements, Sexual selection of ultraviolet and structural color signals, Reproductive biology and phylogeny of birds. 2005; Mougeot et al. There were no significant differences between control and experimental males for the traits measured (morphological traits, feather holes, bib size, and original wing bar size), the only significant difference being manipulated wing bar (Table 1). All rights reserved. Moreover, female house sparrows chose males with larger white wing bars.

Wing-bar size is positively correlated with uropygial gland size, an organ related to resistance against chewing lice (Moreno-Rueda 2010). Adults have black and white stripes on their head, a grey face, brown streaked upper parts and a long tail. The male Italian Sparrow has chestnut upperparts; black patch on throat and breast; pale gray rest of underparts.
