“…Also, in social monogamous species such as these, extra-pair copulations generate an opportunity to intensify a sexual selection process (Webster et al, 2007). Supporting this, high extra-pair copulation was observed in scissor-tailed flycatchers (Roeder et al, 2019).…”

“…These species have disjunct geographical distributions (Regosin, 2020) and are characterised as socially monogamous, with both male and female involved in parental care (Jahn & Tuero, 2020; Regosin & Pruett‐Jones, 1995). Both species show a marked sexual dimorphism in tail length, although both females and males exhibit extremely elongated tails when compared to the other, non‐deep, fork‐tailed Tyrannus species (hereafter, NDF species) (Regosin & Pruett‐Jones, 2001; Roeder et al, 2019; Tuero et al, 2019). Due to their aerodynamic cost, these long tails increase drag in relation to the lift (Evans & Thomas, 1997; Thomas, 1993), making a good example of a structure evolving under a sexual selection mechanism (Balmford et al, 1993).…”

Variational properties hold a fundamental role in shaping biological evolution, exerting control over the magnitude and direction of evolutionary change elicited by microevolutionary processes that sort variation, such as selection or drift. We studied the genus Tyrannus as a model for examining the conditions and drivers that facilitate the repeated evolution of exaggerated, secondary sexual traits in the face of significant functional limitations. In particular, we explore the role of allometry, sexual selection and their interaction, on the diversification of tail morphology in the genus, assessing whether and how they promoted or constrained phenotypic evolution. Non‐deep‐forked species tend to show reduced sexual dimorphism and moderate allometric variation in tail shape. The exaggerated and functionally constrained long feathers of deep‐forked species, T. savana and T. forficatus, which show both marked sexual dimorphism and allometric tail shape variation, independently diverged from the rest of the genus following the same direction of main interspecific variation accrued during the evolution of non‐deep‐forked species. Moreover, the latter direction is also aligned with axes summarising sexual dimorphism and allometric variation on deep‐forked species, a feature lacking in the rest of the species. Thus, exaggerated tail morphologies are interpreted as the result of amplified divergence through reorientation and co‐option of allometric variation by sexual selection, repeatedly driving morphology along a historically favoured direction of cladogenetic evolution.

“…However, there might also be costs associated with multiple mating, such as reduced paternal care to the brood, search costs for additional partners and parasite transmission [18]. Individuals involved in MP are not expected to be a random subset of the adult population [19], and traits correlated with MP in both males and females have attracted considerable attention [19][20][21]. In particular, male secondary sexual traits have been widely investigated in terms of how they affect total mating success [19,[21][22][23].…”

The causes of variation in multiple paternity (MP) in socially monogamous birds have received considerable attention. Traits like age and age-dependent morphology have been shown to be important for the distribution of MP. However, most studies fail to separate between the different processes underlying age-effects on MP, such as selective disappearance (that is, higher survival probability for certain phenotypes) versus individually plastic changes in morphology and mating behaviour with age. Using Bayesian multi-level path analysis on a long-term dataset from a house sparrow (Passer domesticus) metapopulation, we disentangle the effects of age on male and female MP, both independently from and through morphological traits. Age was a key determinant of MP for males when accounting for morphological traits, with males having MP more often as they get older (plastic component of age) and not due to disappearance of males unsuccessful to get MP (selective disappearance), challenging good genes explanations for MP. Conversely, selective disappearance explained the higher levels of MP in older females, suggesting that higher quality females have MP more often than lower quality females. We show how an appropriate statistical decomposition of age-components and age-dependent processes provides insights to the biological drivers of MP.

“…Derived from independent monophyletic lineages [59], these DF species present disjunct geographic distributions [60] and are characterised as socially monogamous, with both male and female involved in parental care [61]. Both species show extremely elongated tails in males and females, as well as a significant sexual dimorphism in tail length attributed to the action of sexual selection [58,62,63].…”

Variational properties hold a fundamental role in shaping biological evolution, exerting control over the magnitude and direction of evolutionary change elicited by microevolutionary processes that sort variation, such as selection or drift. We studied the Tyrannus genus, as a model for examining the conditions and drivers that facilitate the repeated evolution of exaggerated, secondary sexual traits in the face of significant functional limitations. We study the role of allometry, sexual selection, and their interaction on the diversification of tail morphology in the genus, assessing whether and how they promoted or constrained phenotypic evolution. The exaggerated and functionally-constrained long feathers of deep-forked species, T. savana and T. forficatus, independently diverged from the rest of the genus following the same direction of main interspecific variation common to the entire cluster of species. However, at a macroevolutionary scale those axes summarising both sexual dimorphism and allometric variation of the deep-forked species were aligned with the between-species maximum variation axis of non deep-forked species. Thus, we are presenting evidence of amplified divergence via the co-option and reorientation of allometric shape variation involved in a sexual selection process that repeatedly drove morphology along a historically favoured direction of cladogenetic evolution.
