    A New Tapaculo Related to Scytalopus Rodriguezi from Serranía De Los Yariguíes, Colombia

    Thomas M. Donegan et al. 256 Bull. B.O.C. 2013 133(4) A new tapaculo related to Scytalopus rodriguezi from Serranía de los Yariguíes, Colombia by Thomas M. Donegan, Jorge E. Avendaño & Frank Lambert Received 15 February 2013 Summary.―Upper Magdalena Tapaculo Scytalopus rodriguezi was described (in 2005) as restricted to the headwaters of the Magdalena Valley in dpto. Huila, Colombia. Here we describe a new but related taxon from the Serranía de los Yariguíes, dpto. Santander, Colombia, c.580 km to the north, which difers in its darker dorsal coloration, shorter tail, smaller body, lower mass and lower pitched song with reduced frequency bandwidth in its notes. Scytalopus tapaculos are small, primarily montane suboscines that inhabit the understorey of Neotropical forests. Species limits within the genus are problematic because of the morphological homogeneity of diferent populations, which masks a rich diversity, only detected in recent decades via vocal and genetic studies. Since vocalisations are believed to be innate and distinctive among genetically divergent Scytalopus species, and vocal diferentiation tracks molecular diferentiation more so than morphology (Arctander & Fjeldså 1994), the number of recognised species of Scytalopus has increased dramatically from ten in the mid 1990s to more than 40 today (Krabbe & Schulenberg 1997; see also, e.g., Krabbe & Schulenberg 2003, Krabbe & Cadena 2010, Hosner et al. 2013). Four new Scytalopus taxa have been described from Colombia since the late 1990s: Chocó Tapaculo S. chocoensis (Krabbe & Schulenberg 1997), Upper Magdalena Tapaculo S. rodriguezi (Krabbe et al. 2005), Stiles’ Tapaculo S. stilesi (Cuervo et al. 2005) and a subspecies of Pale-bellied Tapaculo S.

Donegan ProAves Foundation, Caversham, Reading, UK. [email protected], [email protected] Jorge Enrique Avendaño-C. 1 Escuela de Biología, Universidad Industrial de Santander, Bucaramanga, Colombia [email protected] ABSTRACT We analysed biometrics, plumage and voice and inspected specimens to study the taxonomy of various high elevation tapaculos Scytalopus of the Eastern Andes of Colombia and the Mérida Andes of Venezuela. In light of a lack of any diagnostic vocal, plumage or biometric character, we propose treating S. infasciatus as a subjective junior synonym of S. griseicollis . S. fuscicauda and S. meridanus are indistinguishable by morphology, but we propose treating S. fuscicauda as a subspecies of S. meridanus in light of small observed differences in introductions to songs, which require further investigation. As the names were published contemporaneously, we propose priority for S. meridanus over S. fuscicauda . S. meridanus and S. griseicollis as redefined are each diagnosable vocally, supporting species rank for both of them. S. griseicollis gilesi subsp. nov. is described from the Yariguíes mountains. The new subspecies differs from S. griseicollis in its darker plumage, lower acoustic frequency scolds and longer tail. The recently discovered Eastern Andes population of S. spillmanni differs from Ecuadorian populations in its shorter tarsus length and slower song, meeting the requirements for some, but not all, subspecies concepts.

Moreover, morphological, ecological and behavioral differences among two lineages of Scytalopus and two species of Pteroptochos are unclear. According to our results, there are no decisive criteria differentiating among subspecific sister taxa of Scelorchilus albicollis , S.rubecula and Pteroptochos megapodius . Here we discuss the speciation of the chilean Rhinocryptidae based in their behaviour. We propose a new methodology based on ecological and behavioural patterns in order to understand the concept of speciation in this group of birds.

We enjoyed great weather for birding, with almost no morning rain throughout the trip, and just a few delightful afternoon and evening showers. Comfortable accommodations, iconic landscapes, abundant, delicious meals, and our charismatic driver Luís enhanced our time in the field. Our group, made up of a mix of first- timers to the tropics and more seasoned tropical birders, got along wonderfully, with some spying their first-ever toucans, motmots, puffbirds, etc. on this trip, and others ticking off regional endemics and hard-to-get species. We were fortunate to have several high-quality mammal sightings, including three monkey species, Derby’s Wooly Opossum, Northern Tamandua, and Tayra.

Variation in acoustic signals may reflect population structure, lack of gene flow, and phylogenetic relationships. In birds, the study of geographic variation in acoustic signals has been useful for elucidating potential factors involved in phenotypic divergence and for establishing species limits. However, most of the studies on geographic variation have focused on calls and solo songs, with few studies focusing on complex behaviors such as duets. In this study, we investigated the variation in the duets of the Rufous-naped Wren (Campylorhynchus rufinucha).

Our tour to magical Costa Rica started in the beautifully arranged gardens of the Hotel Bougainvillea. In these gardens, we came across our first target species of the tour, the Lesson’s Motmot. It was foraging between native and exotic plants, small ponds, vines, bromeliads with brightly colored inflorescence, and flowering orchids. This brought the opportunity to give a brief explanation of old and modern taxonomy and the challenges raised with the development of molecular biology. A good example was indeed this motmot, a species formerly considered as part of the Blue-crowned Motmot and now separated into five species. From San José we drove south, to the Cerro de la Muerte . Once we reached the ridge, we took a short detour to the Paraiso Quetzal where hummingbird feeders provided views of the regional endemic Fiery- throated Hummingbird. There were also Lesser Violetears and Magnificent Hummingbirds. After lunch, the clouds were still dispersed, and there was no sign of rain. Thus, we decided to play with luck and drove to the highest point of the road, to the antenna dirt road.
