Abstract Marcot, Bruce G. 1995. Owls of old forests of the world. Gen. Tech. Rep. PNW- GTR-343. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 64 p. A review of literature on habitat associations of owls of the world revealed that about 83 species of owls among 18 genera are known or suspected to be closely asso- ciated with old forests. Old forest is defined as old-growth or undisturbed forests, typically with dense canopies. The 83 owl species include 70 tropical and 13 tem- perate forms. Specific habitat associations have been studied for only 12 species (7 tropical and 5 temperate), whereas about 71 species (63 tropical and 8 temperate) remain mostly unstudied. Some 26 species (31 percent of all owls known or sus- pected to be associated with old forests in the tropics) are entirely or mostly restricted to tropical islands. Threats to old-forest owls, particularly the island forms, include conversion of old upland forests, use of pesticides, loss of riparian gallery forests, and loss of trees with cavities for nests or roosts. Conservation of old-forest owls should include (1) studies and inventories of habitat associations, particularly for little-studied tropical and insular species; (2) protection of specific, existing temperate and tropical old-forest tracts; and (3) studies to determine if reforestation and vege- tation manipulation can restore or maintain habitat conditions. An appendix describes vocalizations of all species of Strix and the related genus Ciccaba. Keywords: Owls, old growth, old-growth forest, late-successional forests, spotted owl, owl calls, owl conservation, tropical forests, literature review. -

Discovering Great Sandy Region Chapter 5 Animals of the Dunes the Animals of Fraser Island and Cooloola Are Not Readily Apparent to the Casual Observer
DGSR Fauna 1 Discovering Great Sandy Region Chapter 5 Animals of the Dunes The animals of Fraser Island and Cooloola are not readily apparent to the casual observer. The most obvious are birds and dingoes. Despite the obscurity of the fauna it presents an impressive range to those with the patience to explore and discover. This is because much of the fauna is lies buried in the sand or hidden by the great bulk of biomass or else it is either well camouflaged, very timid, or very small. However, it is not necessary to see animals in the wild to be attracted by them. Tens of thousands of anglers are used to searching out invisible targets as they seek the pelagic tailor during the winter months, and bream, whiting trevally and flathead at any time of the year. However, there are many other interesting animals in the sea around Fraser Island and Cooloola than those which delight the anglers. These mammals and reptiles are not the targets of anglers but the subject of much interest of those who are seeking to understand the environment and the many niches in and around Fraser Island and Cooloola. Although Fraser Island and Cooloola lack large populations of bigger terrestrial animals, they boast many rare and unusual species. One study in Cooloola alone identified over 300 species of ants, many new to science. In the aquatic environment the acidity of some of the peaty swamps has been so hostile that a specialized group of frogs known as "acid frogs" has evolved to fill this unique niche. -
Estimations Relative to Birds of Prey in Captivity in the United States of America
ESTIMATIONS RELATIVE TO BIRDS OF PREY IN CAPTIVITY IN THE UNITED STATES OF AMERICA by Roger Thacker Department of Animal Laboratories The Ohio State University Columbus, Ohio 43210 Introduction. Counts relating to birds of prey in captivity have been accomplished in some European countries; how- ever, to the knowledge of this author no such information is available in the United States of America. The following paper consistsof data related to this subject collected during 1969-1970 from surveys carried out in many different direc- tions within this country. Methods. In an attempt to obtain as clear a picture as pos- sible, counts were divided into specific areas: Research, Zoo- logical, Falconry, and Pet Holders. It became obvious as the project advanced that in some casesthere was overlap from one area to another; an example of this being a falconer working with a bird both for falconry and research purposes. In some instances such as this, the author has used his own judgment in placing birds in specific categories; in other in- stances received information has been used for this purpose. It has also become clear during this project that a count of "pets" is very difficult to obtain. Lack of interest, non-coop- eration, or no available information from animal sales firms makes the task very difficult, as unfortunately, to obtain a clear dispersal picture it is from such sourcesthat informa- tion must be gleaned. However, data related to the importa- tion of birds' of prey as recorded by the Bureau of Sport Fisheries and Wildlife is included, and it is felt some observa- tions can be made from these figures. -

From these, we collected a total of 157 owl pellets. Analysis and examination of the pellets revealed 329 prey items. More in-depth investigation determined that 95.1% of the Eastern Grass Owl pellets collected consisted of mammal remains, while the remaining 4.9% were made up of bird remains. Of the various types of mammals consumed, rats made up the highest proportion, with a total of 285 rats, accounting for 86.6%. This was followed by 27 shrews and moles, accounting for 8.2%. Hares and birds were seldom caught and consumed. The findings suggested that rats are the main food source of the Eastern Grass Owl, with the Spinus Country-rat (Rattus losea) comprising the majority with 136 counted (41.3%), followed by the Formosan Mouse (Mus caroli) with 96 counted (29.2%). -
India: Kaziranga National Park Extension
INDIA: KAZIRANGA NATIONAL PARK EXTENSION FEBRUARY 22–27, 2019 The true star of this extension was the Indian One-horned Rhinoceros (Photo M. Valkenburg) LEADER: MACHIEL VALKENBURG LIST COMPILED BY: MACHIEL VALKENBURG VICTOR EMANUEL NATURE TOURS, INC. 2525 WALLINGWOOD DRIVE, SUITE 1003 AUSTIN, TEXAS 78746 WWW.VENTBIRD.COM INDIA: KAZIRANGA NATIONAL PARK EXTENSION February 22–27, 2019 By Machiel Valkenburg This wonderful Kaziranga extension was part of our amazing Maharajas’ Express train trip, starting in Mumbai and finishing in Delhi. We flew from Delhi to Guwahati, located in the far northeast of India. A long drive later through the hectic traffic of this enjoyable country, we arrived at our lodge in the evening. (Photo by tour participant Robert Warren) We enjoyed three full days of the wildlife and avifauna spectacles of the famous Kaziranga National Park. This park is one of the last easily accessible places to find the endangered Indian One-horned Rhinoceros together with a healthy population of Asian Elephant and Asiatic Wild Buffalo. We saw plenty individuals of all species; the rhino especially made an impression on all of us. It is such an impressive piece of evolution, a serious armored “tank”! On two mornings we loved the elephant rides provided by the park; on the back of these attractive animals we came very close to the rhinos. The fertile flood plains of the park consist of alluvial silts, exposed sandbars, and riverine flood-formed lakes called Beels. This open habitat is not only good for mammals but definitely a true gem for some great birds. Interesting but common birds included Bar-headed Goose, Red Junglefowl, Woolly-necked Stork, and Lesser Adjutant, while the endangered Greater Adjutant and Black-necked Stork were good hits in the stork section. -

The Ecology of Four Owl Species with Particular
CHAPTER 1: THE ECOLOGY OF FOUR OWL SPECIES WITH PARTICULAR REFERENCE TO THE GRASS OWL (TYTO CAPENSIS SMITH, 1834) BIOLOGY, HABITAT AND PREY SPECIFICATIONS IN THE EAST RAND HIGHVELD, GAUTENG “Habitats change with time, so that organisms must continually change also in order to adapt” (Maclean, 1990). 1 CHAPTER 1.1: GENERAL BACKGROUND 1.1. GENERAL BACKGROUND A diversity of owls occurs in southern Africa, however this is only 12 of the world’s 135 species. Of these twelve owl species that occur within the sub- continent (Steyn, 1994), four are known to occur in the study area namely the rare African Grass Owl (Tyto capensis), Marsh Owl (Asio capensis), Barn Owl (Tyto alba) and the Spotted Eagle Owl (Bubo africanus) of which the Grass Owl is listed as vulnerable in the Red Data Book. The Barn and Grass owls belong to a genus known as Tyto, the Cape and Spotted Eagle Owls to Bubo, and the Marsh Owls to Asio, which only has one representative in southern Africa (Steyn, 1992). Owls are nocturnal birds of prey that are taxonomically unrelated to the diurnal raptors despite similarities in their predatory habits and weaponry (Steyn, 1984). Owls are separated into two fairly distinct families. The first family is Tytonidae, with typical representatives being T. alba and T. capensis, representing owls of distinct characteristic traits. The most obvious external differences are the general appearance, such as the heart, rather than round shape of the facial disc; the longer skeletal structure and beak; longer legs; longer, more pointed wings and a forked tail. -
