“…For ND1 (in which the min/max are the same), a divergence time off 0.9 and 2.815 mya is found, echoing the estimates calculated for Cytochrome b. Oatley et al (2015) also examined divergence times of the harriers and estimated that the emergence of the Circus clade occurred between 2.7 and 6.6 mya during the expansion of the C4 grasses, followed by the diversification of the steppe harrier clade (in which cyaneus and hudsonius are placed) between 2.2 and 5.5 mya. These estimates overlap and agree well with our estimates of Circus cyaneus divergence times.…”

“…Previous work (Oatley et al 2015) was carried out using a total of 2032 bp from three nuclear genes [Myoglobin intron-2 (MB), Beta Fibrinogen intron-5 (FGB) and TGFβ2 intron-5 (TGFB2)] as well as the mitochondrial ND1 gene from 39 Accipitriformes, which included 16 different Circus taxa. They also showed cyaneus and hudsonius to be separate species, with Circus cinereus (Cinereous Harrier) being a sister species to hudsonius and then cyaneus sister to those two species.…”

“…Recently however, an in-depth molecular phylogeny of all the harrier species was carried out, using one mitochondrial and three nuclear loci and concluded that cyaneus and hudsonius were two distinct species, with Cinereous Harrier (Circus cinereus) being a sister species of hudsonius (Oatley et al 2015). However, despite the different taxonomies employed by previous workers studying Circus cyaneus, no formal systematic treatment of the two forms has been performed.…”

“…However, despite the different taxonomies employed by previous workers studying Circus cyaneus, no formal systematic treatment of the two forms has been performed. Here, we build on previous phylogenetic work (Oatley et al 2015) and carry out a comparative analysis of several key characters associated with the life-history and morphology of the two forms cyaneus and hudsonius and discuss their taxonomic ranking in light of these new perspectives.…”

Background: Circus cyaneus is a medium-sized bird of prey that is widely distributed across the Northern Hemisphere. There are two currently recognized forms, the Palearctic form C. c. cyaneus (Hen Harrier), and the Nearctic form C. c. hudsonius (Northern Harrier). The forms have recently been split by the British Ornithologists' Union but the American Ornithologists' Union and some other taxonomic committees have not yet made any change. Here we examine the phylogenetic relationship between the two forms using sequence data from multiple nuclear and mitochondrial genes and examine breeding biology, body size, morphology, dispersal and other behaviors. Methods:In order to fully compare cyaneus and hudsonius, we carried out a full literature review, measured museum skins and carried out phylogenetic analysis using a number of different mitochondrial genes and compare our findings to other recent work. Results:We find that these two allopatric taxa form reciprocally monophyletic groups, show substantial mtDNA sequence divergence, and further differ significantly with respect to body size, plumage characters, breeding biology, dispersal and other behavioral traits. Conclusions:Based on an array of consistently divergent characteristics, it is suggested that the two forms are best regarded as separate species, Hen Harrier (Circus cyaneus) and Northern Harrier (Circus hudsonius).

Broodmate aggression and life history variation in accipitrid birds of prey

Aggressive sibling competition for parental food resources is relatively infrequent in animals but highly prevalent and extreme among certain bird families, particularly accipitrid raptors (Accipitriformes). Intense broodmate aggression within this group is associated with a suite of traits including a large adult size, small broods, low provisioning rates, and slow development. In this study, we apply phylogenetic comparative analyses to assess the relative importance of several behavioral, morphological, life history, and ecological variables as predictors of the intensity of broodmate aggression in 65 species of accipitrid raptors. We show that intensity of aggression increases in species with lower parental effort (small clutch size and low provisioning rates), while size effects (adult body mass and length of nestling period) are unimportant. Intense aggression is more closely related to a slow life history pace (high adult survival coupled with a restrained parental effort), rather than a by‐product of allometry or food limitation. Consideration of several ecological variables affecting prey abundance and availability reveals that certain lifestyles (e.g., breeding in aseasonal habitats or hunting for more agile prey) may slow a species’ life history pace and favor the evolution of intense broodmate aggression.
