Telecrex Restudied: a Small Eocene Guineafowl
TELECREX RESTUDIED: A SMALL EOCENE GUINEAFOWL STORRS L. OLSON In reviewing a number of the fossil species presently placed in the Rallidae, I have had occasion to examine the unique type-an incomplete femur-of Telecrex grangeri Wetmore (1934)) described from the Upper Eocene (Irdin Manha Formation) at Chimney Butte, Shara Murun region, Inner Mongolia. Although Wetmore assigned this fossil to the Rallidae, he felt that the species was distinct enough to be placed in a separate subfamily (Telecrecinae) ; this he considered to be ancestral to the modern Rallinae. After apparently ex- amining the type, Cracraft (1973b:17) assessed it as “decidedly raillike in the shape of the bone but distinct in the antero-posterior flattening of the head and shaft.” However, he suggested that Wetmores’ conclusions about its relationships to the Rallinae would have to be re-evaluated. Actually, Tele- crex bears very little resemblance to rails, and the distinctive proximal flat- tening of the shaft (but not of the head, contra Cracraft) is a feature peculiar to certain of the Galliformes. Further, my comparisons show Telecrex to be closest to the guineafowls (Numididae), a family hitherto known only from Africa and Europe. DISCUSSION The type specimen of Telecrex grangeri (AMNH 2942) is a right femur, lacking the distal end and part of the trochanter (Fig. 1). Its measurements are: proximal width 11.6 mm, depth of head 4.2, width of shaft at midpoint 4.6, depth of shaft at midpoint 4.1, overall length (as preserved ) 46.1. Telecrex differs from all rails -

The influence of space and time on the genetic architecture of rail species (Aves: Rallidae) A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Evolutionary Ecology at Massey University, Palmerston North, New Zealand JUAN CARLOS GARCIA RAMIREZ 2014 Abstract The main subject of this PhD research is the study of the underlying processes of evolutionary changes that lead to biological diversity. Such processes include those operating within and between populations (population divergence), as well as those operating among species (speciation), above the species level (e.g. genera and families) and the mechanisms that promote these divisions. Fundamental to these processes are the effects of genetic, demographic, geographical, ecological, behavioural and environmental factors on diversification. Rails (Aves: Rallidae) are used as an example to address central questions related to how these biological entities originated, when was that biological diversity generated, and why this biodiversity is distributed as it is. This thesis has been divided into four main chapters/papers for convenience to achieve this aim. In the first chapter, complete mitochondrial genomes and fossil data are used to provide a likely estimated time of rail ecology. I estimated that the origin and diversification of crown group Rallidae was during the Eocene about 40.5 (49–33) Mya with evidence of intrafamiliar diversification from Late Eocene to Miocene time. -
Birding Oxley Creek Common Brisbane, Australia
Birding Oxley Creek Common Brisbane, Australia Hugh Possingham and Mat Gilfedder – January 2011 [email protected] www.ecology.uq.edu.au 3379 9388 (h) Other photos, records and comments contributed by: Cathy Gilfedder, Mike Bennett, David Niland, Mark Roberts, Pete Kyne, Conrad Hoskin, Chris Sanderson, Angela Wardell-Johnson, Denis Mollison. This guide provides information about the birds, and how to bird on, Oxley Creek Common. This is a public park (access restricted to the yellow parts of the map, page 6). Over 185 species have been recorded on Oxley Creek Common in the last 83 years, making it one of the best birding spots in Brisbane. This guide is complimented by a full annotated list of the species seen in, or from, the Common. How to get there Oxley Creek Common is in the suburb of Rocklea and is well signposted from Sherwood Road. If approaching from the east (Ipswich Road side), pass the Rocklea Markets and turn left before the bridge crossing Oxley Creek. If approaching from the west (Sherwood side) turn right about 100 m after the bridge over Oxley Creek. The gate is always open. Amenities The main development at Oxley Creek Common is the Red Shed, which is beside the car park (plenty of space). The Red Shed has toilets (composting), water, covered seating, and BBQ facilities. The toilets close about 8pm and open very early. The paths are flat, wide and easy to walk or cycle. When to arrive The diversity of waterbirds is a feature of the Common and these can be good at any time of the day. -

Los juveniles son en general más claros, sin negro en la cabeza y presentan una mancha blanca en el mentón y garganta. En el adulto el pico es fuerte y de color amarillo anaranjado, con una mancha negra en el culmen; en tanto que en los juveniles, el pico es negro verdoso con ligero tinte café. Las piernas en adultos y juveniles son de color verdoso, tirando al café con tinte gris oscuro a nivel de las articulaciones. Los dedos lobulados y provistos de poderosas uñas, son de gran tamaño, llegando a medir entre 20 y 30 cm de largo el dedo mayor. Los pies de los machos son apreciablemente más grandes que las de las hembras (Goodall et al. 1964, Araya et al. 1998, Martínez & González 2004, Jaramillo 2005). En los polluelos las piernas son negras, pero el pico es rosado con punta negra y amarilla y el cuerpo cubierto de un plumón fino y completamente negro, a excepción de una pequeña zona de plumillas blanquecinas en el mentón. El iris en el polluelo y en el ave juvenil es de color café, cambiando progresivamente mientras avanza a la adultez, hasta adquirir el característico color café anaranjado (Goodall et al. -

WALKING WATERBIRDS unmistakable, elegant wader; no similar species in Chile SHOREBIRDS For ID purposes there are 3 basic types of shorebirds: 6 ‘unmistakable’ species (avocet, stilt, oystercatchers, sheathbill; pp. 89–91); 13 plovers (mainly visual feeders with stop- start feeding actions; pp. 92–98); and 22 sandpipers (mainly tactile feeders, probing and pick- ing as they walk along; pp. 99–109). Most favor open habitats, typically near water. Different species readily associate together, which can help with ID—compare size, shape, and behavior of an unfamiliar species with other species you know (see below); voice can also be useful. 2 1 5 3 3 3 4 4 7 6 6 Andean Avocet Recurvirostra andina 45–48cm N Andes.

A Classification of the Rallidae
A CLASSIFICATION OF THE RALLIDAE STARRY L. OLSON HE family Rallidae, containing over 150 living or recently extinct species T and having one of the widest distributions of any family of terrestrial vertebrates, has, in proportion to its size and interest, received less study than perhaps any other major group of birds. The only two attempts at a classifi- cation of all of the recent rallid genera are those of Sharpe (1894) and Peters (1934). Although each of these lists has some merit, neither is satisfactory in reflecting relationships between the genera and both often separate closely related groups. In the past, no attempt has been made to identify the more primitive members of the Rallidae or to illuminate evolutionary trends in the family. Lists almost invariably begin with the genus Rdus which is actually one of the most specialized genera of the family and does not represent an ancestral or primitive stock. One of the difficulties of rallid taxonomy arises from the relative homo- geneity of the family, rails for the most part being rather generalized birds with few groups having morphological modifications that clearly define them. As a consequence, particularly well-marked genera have been elevated to subfamily rank on the basis of characters that in more diverse families would not be considered as significant. Another weakness of former classifications of the family arose from what Mayr (194933) referred to as the “instability of the morphology of rails.” This “instability of morphology,” while seeming to belie what I have just said about homogeneity, refers only to the characteristics associated with flightlessness-a condition that appears with great regularity in island rails and which has evolved many times.
