“…Notes.-Through the fifth edition of the check-list, the AOU (1957) recognized the monotypic genus Rhynchophanes for Calcarius mccownii. Subsequently (Paynter 1970;AOU 1983AOU , 1998, Rhynchophanes was merged with Calcarius, evidently on the basis of a hybrid R. mccownii × C. ornatus (Sibley and Pettingill 1955). Klicka et al (2003), using mitochondrial data, found Calcarius as presently recognized to be paraphyletic: mccownii is more closely related to the Plectrophenax buntings than to the other species in Calcarius, consistent with some evidence of morphological differences among these three groups (Baird 1858).…”

We use information technology and tools to increase productivity and facilitate new forms of scholarship. For more information about JSTOR, please contact support@jstor.org.. American Ornithologists' Union is collaborating with JSTOR to digitize, preserve and extend access to The Auk. Changes in this supplement include the following: (1) one genus (Chrysomus) and eight species (Oceanodroma monorhis, Ixobrychus minutus, Ardea purpurea, Platalea leucorodia, Glareola pratincola, Elaenia albiceps, Luscinia sibilans, and Chrysomus icterocephalus) are added to the main list (including three species transferred from the Appendix) on the basis of new distributional information; (2) the distributional statement of one species (Trogon melanurus) is changed because of a split from an extralimital species; (3) three species are changed (to Melanitta americana, Trogon caligatus, and T. chionurus) by being split from extralimital species; (4) six species (Caprimulgus arizonae, Chasiempis sclateri, C. ibidis, Icterus northropi, I. melanopsis, and I. portoricensis) are added as a result of splits from species already on the list; (5) two species (Troglodytes hiemalis and T. pacificus) are added by being split both from an extralimital taxon (T. troglodytes) and from each other; (6) five species (Melozone fusca, M. albicollis, M. crissalis, M. aberti, and Amphispiza quinquestriata) are transferred to currently recognized genera; (7) five genera (Psilorhinus, Peucaea, Oreothlypis, Parkesia, and Rhynchophanes) are added because of splits from other genera, resulting in changes to 20 scientific names; (8) a new scientific name (Vermivora cyanoptera) is adopted for one species because of a nomenclatural problem with the previous scientific name (V. pinus); (9) the citation for one species (Dendroica pinus) is changed; (10) the endings of the specific or subspecific names of two taxa (Acanthidops bairdi and Vireo gilvus swainsoni) are corrected; (11) the English names of three species (Caprimulgus vociferus, Chasiempis sandwichensis, and Icterus dominicensis) are modified as a result of taxonomic changes, the English name of one species (Puffinus gravis) is modified for global conformity, and the hyphen is removed from the English name of one species (Empidonomus aurantioatrocristatus); and (12) two species (Empidonomus aurantioatrocristatus and Thryothorus sinaloa) are added to the list of species known to occur in the United States.Numerous changes are made at higher levels of the classification on the basis of new genetic data. Four newly recognized orders (Phaethontiformes, Suliformes, Accipitriformes, and Eurypygiformes) are added to the main list by being split from existing 29_Supplement_127-3.indd 726 7/2/10 12:41:48 PM

“…However, Klicka et al (2003) have still suggested considering that the entire Calcarius/ Plectrophenax clade be collapsed down to the older generic epithet Calcarius, splitting C. lapponicus from the collared longspurs completely. The presence of the snow bunting × Lapland longspur hybrid could increase confidence in this idea, although hybrids are already known between more distantly related species in the Calcariidae family (i.e., R. mccownii × C. ornatus; Sibley and Pettingill, 1955). Although hybridization between non-sister avian species is well known (see Prager and Wilson, 1975), Klicka et al (2003) have noted that the ability to hybridize should not be uncritically interpreted as evidence of close phylogenetic relationship.…”

“…The family Calcariidae consists of the genera Calcarius, Rhyncophanes, and Plectrophenax, forming a highly supported evolutionary group or "clade" composed of three sub-clades: a "collared" longspur clade of Calcarius lapponicus, ornatus, and pictus; a "snow bunting" clade comprising two Plectrophenax species (nivalis and hyperboreus); and one Rhyncophanes longspur species (mccownii) (Klicka et al, 2003;Alström et al, 2006;Chesser et al, 2010). Hybridization has been reported among the longspurs (e.g., R. mccownii × C. ornatus; Sibley and Pettingill, 1955), as well as between the closely related Plectrophenax species (Sealy, 1969;Maley and Winker, 2010;references in McCarthy, 2006). There are also reports of fertile eggs being produced (no hatched hybrids) from a cross of an Emberizidae species (yellowhammer -Emberiza citrinella) and P. nivalis (Fitzpatrick, 1951in McCarthy, 2006 even though longspurs and buntings are no longer considered to be closely related to the Emberizidae (Chesser et al, 2010).…”

First Report of a Snow Bunting × Lapland Longspur Hybrid

In late April 2011, photographs of an apparent male snow bunting (Plectrophenax nivalis) × Lapland longspur (Calcarius lapponicus) hybrid were taken at St. Lewis Inlet, Newfoundland and Labrador, Canada, while the bird was foraging in a mixed flock of both species along a previously documented spring migratory route. As far as we are aware, this is the first hybridization of these species documented anywhere in the world. The bird was identified as a male on the basis of longspur nape coloration, and it appears to have the head, beak, and back coloration and patterning of a Lapland longspur, but the chin, chest and throat, and overall appearance of a snow bunting. Although our research team has banded more than 50 000 birds of both species over the past 30 years across the latitudinal range of both species, we have never observed such a hybrid. While these Arctic-breeding species overlap spatially and temporally during wintering, migration, and breeding, longspurs and buntings have distinct sexual characters and breed in different ecological niches, which may account for the reproductive isolation or low rates of hybridization of these species. While we were unable to conduct detailed morphological or genetic comparisons on this particular individual for phylogenic interpretation, this report highlights the importance of reporting field observations that may indicate ecological changes affecting the hybridization rates of these inaccessible Arctic species.
