Data from: Plumage colouration and social context influence male investment in song
Animals use multiple signals to attract mates, including elaborate song, brightly coloured ornaments and physical displays. Female birds often prefer both elaborate male song, and intense carotenoid-based plumage colouration. This could lead less visually ornamented males to increase song production to maximize their attractiveness to females. We tested this possibility in the highly social and non-territorial house finch (Haemorhous mexicanus), in which females discriminate among males based on both song, and on the intensity of red carotenoid-based plumage colouration. We manipulated male plumage colouration through carotenoid supplementation during moult, so that males were either red or yellow. Males were then housed under three social environments: 1) all red birds, 2) all yellow birds, or 3) a mixture of red/yellow birds. We recorded song after presentation of a female. Red males produced more song than yellow males. But when yellow males were housed with red conspecifics, they produced more song relative to yellow males housed with equally unattractive yellow males. This study provides novel evidence that a male's plumage colouration, and the plumage colour of his social competitors influences investment in song.
Wilson Warbler molting and plumage observations
<p>I made observations of a central California population of Wilson's Warbler, <em>Cardellina pusilla, </em>on or after 1 July over ten breeding seasons. I sighted males in definitive prebasic molt as early as 4 July (in 2007) and as late as 1 September (in 1999). I determined that most territorial males at my study site molted on their breeding territories, and individual molt lasted a maximum of 46 days. Following prebasic molt, territorial males engaged in subdued "post-molt singing," which appeared to last no more than seven days in most males, and which I first heard on 13 August (in 1004), and last heard on 6 September (in 1999). I sighted no female in definitive prebasic molt, nor fresh basic plumage, during the study. Of 13 females sighted on or after 21 July, I confirmed that 11 were in late breeding season uniparental brood care, and I could not rule out late brood care for the other two. Most, and possibly all, females not engaged in late season uniparental brood care appear to have vacated their breeding territories before 21 July, as I saw just two possible after that date. This apparent early departure of the majority of resident females from their breeding grounds was much earlier than the departures of resident males, the last of which I sighted on 10 September (in 1999). Early-departing females presumably underwent prebasic molt after 21 July, and at locations not known. Remaining late-nesting females must have molted much later than did resident males, and also likely later than early-departing resident females, and at unknown locations. I last sighted two uniparental brood-tending females, still in worn plumage, on 26 and 29 August respectively, whereas some males had completed prebasic molt as early as 13 August. Two unique findings of this study are a male/female difference in location of prebasic molt, and a likely dichotomy of prebasic molt timing between females which leave their breeding territories relatively early, and those which remain on their territories in uniparental brood care. Another finding, that most, and perhaps all, territorial male Wilson's Warblers engaged in brief post-molt singing following prebasic molt, is a largely unrecognized behavior, but one previously reported in several other passerine species. Post-molt singing may be a reliable indicator that prebasic molt is complete.</p>
