“…We searched the literature for any reference to female song in each of the 107 warbler species represented in Lovette et al's (2010) molecular phylogeny. We used primary literature, field guides, Neotropical Birds Online, the Birds of North America Online, and the Handbook of the Birds of the World (Del Hoyo et al, 2011).…”

“…Making use of recently published molecular phylogenies resolving the relationships among warblers (Lovette et al, 2010;Barker et al, 2015) we reconstructed the evolution of female song in this group and we tested for correlations among female song, dichromatism, and migratory behavior to investigate the possible relationships among these life history traits. Following the hypothesis that non-migratory, monogamous species with similar sex roles are more likely to express female song (Morton, 1996;Benedict, 2008;Price, 2009), we predicted that gains of female song in warblers would be strongly correlated with losses of migration and losses of dichromatic plumage.…”

Recent advances have revealed that female birdsong is widespread and multifunctional. Female song was likely ancestral among songbirds and persists in many lineages today. Nevertheless, many species lack female song, and researchers are interested in understanding the selective factors that promote and counter the persistence of this trait. Female song is associated with life-history traits including year-round territoriality, non-migratory behavior, sexual monochromatism, and monogamy. Most studies examining these relationships have looked at clades with a migratory ancestor and have found that gains of migratory behavior are strongly correlated with losses of female song (and duetting). Here, we ask if the reverse pattern exists: in a large clade of songbirds with a migratory ancestor, do losses of migratory behavior correlate with gains of female song and visual signaling traits? We investigated correlations between female song, migration, and dichromatism in 107 species of New World Warblers (Family Parulidae). All of these species are predominantly monogamous and territorial when breeding, 50 (47%) are migratory, 49 (46%) are monochromatic, and 25 (23%) show female song. On a robust genetic phylogeny maximum likelihood methods recover migration and monochromatism as the ancestral state in warblers. Female song is generally not reconstructed as present in any deep nodes of the phylogeny, suggesting that most extant species with female song evolved this trait independently and relatively recently. Gains of female song do not correlate with losses of migration. Losses of dichromatism do correlate with losses of migration. Thus, in this clade, visual signals are associated with sedentary vs. migratory lifestyles, but female acoustic signals are not. Our results show a different pattern from that seen in similar studies and support the hypothesis that losses, but not gains, of female song are driven by life history.

“…De récentes recherches en génétique ont démontré, à l'aide de l'ADN mitochondrial, que le genre Oporornis devrait être inclus dans le genre Geothlypis (Escalante et al 2009;Lovette et al 2010) ce qui pourrait laisser supposer des affinités physiologiques, biologiques et comportementales avec d'autres espèces comme la Paruline masquée {Geothlypis trichas).

Les analyses ont démontré que les mâles en couple chantent moins que les mâles seuls. Les célibataires ont un patron de chant très régulier en pleine période de reproduction où les autres mâles (en couple) réalisent d'autres tâches en lien avec la nidification. Ceux qui se reproduisent, ont de quatre à cinq oeufs par nid qui sont incubés par la femelle uniquement, et ce pendant 11 jours. Après l'éclosion, les deux parents s'occupent des soins apportés aux jeunes (nourriture, sac fécal, thermorégulation), mais la nuit, il n'y a que la femelle qui les couve. Les jeunes quittent le nid vers huit jours. L'activité principale de la femelle est de couver les jeunes et celle du mâle est de chercher de la nourriture (hors du nid). Cela change pour la femelle à mesure que les jeunes grandissent, elle a moins besoin de réchauffer les jeunes et s'implique plus dans la recherche de nourriture. Les jeunes semblent être en mesure de réguler seul leur température corporelle vers l'âge de sept jours.Les deux adultes visitent le nid à un taux similaire et celui-ci augmente en même temps que les jeunes vieillissent, car ils ont besoin de plus en plus de nourriture. Les mâles retirent beaucoup plus de sacs fécaux que les femelles et le nombre de sacs augmentent avec l'âge des jeunes, puisqu'ils mangent davantage. Les adultes ingurgitent les sacs fécaux surtout lorsque les oisillons sont jeunes et les transportent de plus en plus à mesure qu'ils grandissent.Pour le second sous-objectif, nous avons utilisé des microsatellites créés pour deux autres espèces et qui amplifiaient également avec des oiseaux du genre Oporornis. Cinq loci ont n été utilisé pour déterminer l'affiliation parentale malgré le fait que l'équilibre d'HardyWeinberg n'était pas rencontré (sans doute en raison du faible échantillonnage). Une étude plus approfondie avec davantage d'échantillons et en ciblant d'autres loci permettrait de réaliser plus efficacement l'affiliation parentale. Néanmoins, avec 5 loci et seulement 3 nids testés nos résultats suggèrent que les pères sociaux étaient également les géniteurs. Ce qui signifie qu'aucune copulation extra-couple ayant donnée un jeune n'a été reconnue pour ces nids. Pour ce qui est de la détermination du sexe des individus, nous avons utilisé une technique connue, mais non évaluée sur la Paruline à gorge grise jusqu'à ce jour et démontré que cette méthode fonctionne avec cette espèce. ni REMERCIEMENTS

“…To account for phylogenetic autocorrelation due to shared evolutionary history, we used the phylogeny of Lovette et al (2010) for relationships among wood warblers (Parulidae) and that of Gibson and Baker (2012) for relationships among shorebirds (Scolopacidae), both with Pagel's arbitrary branch lengths (Pagel, 1992; calculated with PDAP-PDtree in Mesquite (Maddison and Maddison, 2004;Midford et al, 2005)). We accounted for phylogenetic relatedness among species using phylogenetic generalized least squares regressions implemented in R version 2.15.2 (R Core Development Team, 2012) using the package 'caper' (Orme et al, 2012).…”

Life history as a constraint on plasticity: developmental timing is correlated with phenotypic variation in birds

2015

Understanding why organisms vary in developmental plasticity has implications for predicting population responses to changing environments and the maintenance of intraspecific variation. The epiphenotype hypothesis posits that the timing of development can constrain plasticity-the earlier alternate phenotypes begin to develop, the greater the difference that can result amongst the final traits. This research extends this idea by considering how life history timing shapes the opportunity for the environment to influence trait development. We test the prediction that the earlier an individual begins to actively interact with and explore their environment, the greater the opportunity for plasticity and thus variation in foraging traits. This research focuses on life history variation across four groups of birds using museum specimens and measurements from the literature. We reasoned that greater phenotypic plasticity, through either environmental effects or genotype-by-environment interactions in development, would be manifest in larger trait ranges (bills and tarsi) within species. Among shorebirds and ducks, we found that species with relatively shorter incubation times tended to show greater phenotypic variation. Across warblers and sparrows, we found little support linking timing of flight and trait variation. Overall, our results also suggest a pattern between body size and trait variation, consistent with constraints on egg size that might result in larger species having more environmental influences on development. Taken together, our results provide some support for the hypothesis that variation in life histories affects how the environment shapes development, through either the expression of plasticity or the release of cryptic genetic variation.
