On Paired Ovaries ¾ol.1935 LII] J GeneralNotes. 329 From three feet below the surface in the humus layer at Los Tamarindos, which in point of antiquity antedatesthe time of the Spanishdiscovery (as no glassbeads or iron objects are found among the human artifacts), the following birds are identi- fied: Brazilian Cormorant (Phalacrocoraxolivaceus) and the Horned Screamer (An- hima cornuta). In the deeperlayers, from six to eleven feet from the surface,the following were obtained:Pied-billed Grebe (Podilymbus podiceps), Brazilian Cormorant (Phalacro- coraxolivaceus), Cocoi Heron (Ardea cocoi),Egret (Casmerodiusalbus), Wood Ibis ( Mycteria americana), Gray-breasted Tree-duck (Dendrocygnaautumnalis discolor), Fnlvous Tree-duck (Dendrocygnabicolor), White-faced Tree Duck (Dendrocygna viduata), Black-collared Hawk (Busarellusnigricollis), Red-winged Hawk (Hetero- spiziasmeridionalis), another Hawk of the genusButeo, Curassow (Crax alberti),Purple Gallinule(Ionornis martinica), Gallinnle (Gallinula chloropus), Rusty Dove (Leptotila verreauxi),a large Macaw (Ara sp.), an Amazon Parrot (Amazonasp.), a small Paroquetof uncertaingenus, and the Cayenne0wl (Rhinoptynxclamator). The midden depositsat the Hacienda Tocor6n yielded the following: Brazilian Cormorant (Phalacrocoraxolivaceus), an Ibis (Guarasp.), Horned Screamer(Anhima cornuta), Gray-breasted Tree-duck (Dendrocygnaautumnalis discolor),White-faced Tree-duck (Dendrocygnaviduata), Baldpate (Mareca americana), Muscovy Duck (Cairina moschata),Limpkin (Aramus scoIopaceus),and a Gallinule (Gallinula chloropus). In the sandpit at Cascabelthere was found a humerus of the White-faced Tree- duck (Dendrocygna viduata). The Baldpate, representedby a left humerus lacking the head, has not been recorded previously, so far as I am aware, from Venezuela. The other birds are thosethat are to be expectedin this locality, the majority beingforms that frequent aquatic or m•rshy habitats.--AL•x•n W•Tnon•, U.S. National Museum, Washington,D.C. On P&ired Ov&ries.--The persistenceof but a singleovary, the left, is the normaJ condition in birds, though there are well known exceptions. The work of Gunn,' KummerlSwe? FitzpatrickS and many others, but especially that of Gunn, has brought out the fact that bilateral development of ovaries is not uncommon in Hawks. In the gene•aAccipiter, Circus and Falcothe bilateralcondition may be as common as the unilateral condition. Occasional instances were recorded of the presenceof paired ovariesin quite unrelatedspecies as Grebe, Fulmar, •)uck, Swan, Grouse,Rail, Gull, Woodcock,0wl, Thrush, Rook and Sparrow. While in Madagascarand New Guinea,collecting birds for the AmericanMuseum, I noted the bilatera• developmentof ovariesin somespecies of Hawks, but not in others, and alsofound this condition not unusualin certain Parrots and Lories. Its occurrencein Parrotsand Lories has apparently not beenrecorded. In the species I examinedthe right ovary varied from one-fourth the size to nearly the same size as the left. In somecases the right ovary showedsome enlargement but in no instance did this enlargementapproach a breedingcondition. Rudimentsof a right oviduct were found but in no instancedid it appear functional. The followingis a list of the speciesin which I observed•ight ovariespresent. (The numberof specimensexamined of the Madagascarspecies was not kept care- fully.) 1912, Proceedings Zoological Society, London, pp. 72, 73. 1931, Zeitschr. f. mikroskop.-•n•tom. Forschung, 24, pp. 614-621. 1934, Wilson Bulletin, XLVI, pp. 19-22. 330 GeneralNotes. [July[-Auk No. females with No. females right ovary present examined Machaerhamphusanderssoni 1 Haliastur sphenurus 1 Accipiter madagascariensis 2 Accipiterfrancesii 11 A ccipiterfasciatus 5 Accipiter novaehollandiae 1 Circus aeruginosus 1 Gymnogenysradiatus 1 Ieracidea berigora 2 2 Coracopsisnigra Several Chalcopsittascintillata 1 3 Trichoglossushaematodus 1 8 Eelecrus roratus 2 4 Psittacella brehmii i 5 Thus the presenceof a right ovary seemsnot uncommon in certain Parrots and Lories as well as in some Hawks. Some of Itiddle's• work, done some time ago, is suggestivein this connection. Working with Pigeons,he found some females with persistent right ovaries and observedthat this condition occurred almost wholly in females hatched from eggs otherwiseknown to have the greatestor strongestfemale producingtendency, and from which a high per cent of femaleshatched. May it be that the not uncommonpersistence of a right ovary in certain groups of birds is indicative of a tendency toward femalenessin these species,and further- more may be expressedin the sex ratio, there being a larger number of femalesthan males in these forms? I have no data on the sex ratios of these birds, but possibly there is some such correlation as suggestedabove. There seemsto be no general correlation between the developmentof bilateral ovaries and sexual dimorphism. In the Hawks the chief sexual differenceconsists of the females being larger; in Eclectusroratus the female is slightly smaller and largely red, while the male is larger and chiefly green. In Psitacellabrehmii the male is brighter and slightly larger. In the other Parrots there is little difference betweenthe sexesexcept the slightly smallersize of the female.--A. L. I{xNn, Amer.

SCOTT ECHOLS, DVM, D ipl ABVP-A vian Renal diseases and their various classifications are well documented in the avian literature. The precise patho- genesis of avian renal disease, however, is not nearly as well described as it is in mammals. Renal disease has been shown to be fairly common in avian species. In studied poultry, as much as 29.6% of all disease condi- tions had abnormal pathology associated with or attrib- utable to renal disorders.20,214,251 Amyloidosis, urate nephrosis and gout were the most common diseases associated with mortality in a 4-year retrospective study conducted at a waterfowl park in Ontario, Canada.210 Thirty-seven percent of all avian cases presenting with renal tissue for histopathological examination, included over a 15-month period at the Schubot Exotic Bird Health Center, had one or more histologically identified kidney lesions.187 Nine of 75 pheasants (Phasianus colchicus) died with nephritis, one or both ureters impacted, and visceral gout in another comprehensive study on avian mortality.186 These case reports and retro- spective studies support the conclusion that renal dis- eases are relatively common and are clinically significant in multiple avian species. When compared to mammalian counterparts, the avian urogenital system has many structural and functional differences, which have been described previously.77,90,118,181,187,227 Differences including gross anatomy, renal portal blood flow and protein waste elimination should be considered when reviewing this chapter, as findings obtained from mammalian studies may not necessarily be applicable to birds.

  • Birds at Woodland Park Zoo Pre-Visit Information for Teachers
    BIRDS AT WOODLAND PARK ZOO PRE-VISIT INFORMATION FOR TEACHERS If you are planning a zoo field trip and wish to have your students focus on birds during their visit, this pre-visit sheet can help them get the most out of their time at the zoo. We have put together an overview of key concepts related to birds, a list of basic vocabulary words, and a checklist of bird species at Woodland Park Zoo. Knowledge and understanding of these main ideas will enhance your students’ zoo visit. OVERVIEW: There are over 10,000 species of birds currently identified worldwide, inhabiting a number of different biomes and exhibiting a range of adaptations. Woodland Park Zoo exhibits a wide variety of bird species (see attached checklist) in several different areas of the zoo. A bird field trip to the zoo could focus on the characteristics of birds (see “Concepts” below), comparing/contrasting different birds or learning about biomes and observing the physical characteristics of birds in different biomes. CONCEPTS: Birds share the following physical characteristics: Feathers Endothermic (warm-blooded) Eggs with shell and yolk Lack teeth, but have bony beaks Lightweight skeleton, bones with air spaces Good vision Adaptations for flight: Low body weight Streamlined form Efficient metabolism Specialized respiration and circulation Birds, like all plants and animals, have five basic needs to survive—food, water, shelter, air and space. They inhabit every continent on the planet and range in size from the bee hummingbird at 0.05 ounces (1.6 grams) to the North African ostrich at 275 pounds (125 kilograms).

FLEURY AND THOMAS W. SHERRY Departmentof Ecology,Evolution, and Organismal Biology, Tulane University, New Orleans, Louisiana 70118, USA Al•sTl•C•r.--Long-termpopulation dynamics of colonialwading birds (Ciconiiformes) were examinedusing data from Audubon ChristmasBird Counts(CBC, 1949-1988)and Breeding Bird Surveys(BBS, 1966-1989). Winter populationsof Louisianawading birds increased dramaticallyover the 40-yearperiod, with the sharpestincreases occurring during the last 20 years.Several species populations grew exponentiallyfrom 1968to 1988.High overall positivecovariance was found in the abundanceof the variousspecies over time, and cluster analysisshowed that the specieswith similardietary requirements and foraginghabits cov- ariedmost strongly and positivelywith eachother. Trend analysis of CBCand BBSdata from 1966-1989and 1980-1989showed a closecorrespondence between CBC and BBStrends in Louisiana.Most speciesincreased in Louisianaat the sametime as they declined in Florida andTexas. Several factors might explain increases in populationsof wadingbirds in Louisiana, includinglong-term recovery from the effectsof humanexploitation, expansion of breeding populationsin more northern states,changes in weather,recovery from DDT and similar pesticides,and regionalmovements due to habitatloss in other coastalstates. These hypoth- esesare not mutuallyexclusive

Species highlighted in RED are the ones illustrated with photos in this report. INTRODUCTION Not everyone is fortunate enough to visit Peru; a marvelous country that boasts a huge country bird list, which is second only to Colombia. Unlike our usual set departure, we started out with a daylong extension to Lomas de Lachay first, before starting out on the usual itinerary for the main tour. On this extra day we managed to 1 www.tropicalbirding.com +1-409-515-0514 [email protected] Page Tropical Birding Trip Report PERU: Manu and Machu Picchu Aug-Sept. 2015 find many extra birds like Peruvian Thick-knee, Least Seedsnipe, Peruvian Sheartail, Raimondi’s Yellow- Finch and the localized Cactus Canastero. The first site of the main tour was Huacarpay Lake, near the beautiful Andean city of Cusco (accessed after a short flight from Lima). This gave us a few endemic species like Bearded Mountaineer and Rusty-fronted Canastero; along with other less local species like Many-colored Rush-tyrant, Plumbeous Rail, Puna Teal, Andean Negrito and Puna Ibis. The following day we birded along the road towards Manu where we picked up birds like Peruvian Sierra-Finch, Chestnut-breasted Mountain-Finch, Spot-winged Pigeon, and a beautiful Peruvian endemic in the form of Creamy-crested Spinetail. We also saw Yungas Pygmy-Owl, Black-faced Ibis, Hooded and Scarlet-bellied Mountain- Tanagers, Red-crested Cotinga and the gorgeous Grass-green Tanager.

  • Anhima Cornuta (Horned Screamer) Family: Anhimidae (Screamers) Order: Anseriformes (Waterfowl) Class: Aves (Birds)
    UWI The Online Guide to the Animals of Trinidad and Tobago Ecology Anhima cornuta (Horned Screamer) Family: Anhimidae (Screamers) Order: Anseriformes (Waterfowl) Class: Aves (Birds) Fig. 1. Horned screamer, Anhima cornuta. [http://carnivoraforum.com/topic/10432366/1/, downloaded 1 March 2017] TRAITS. The horned screamer Anhima cornuta is a large bird (Fig. 1) which grows to 84-95cm in length and weighs approximately 3.5kg. The bill looks similar to that of a chicken, and the top half of the body is black, with small white spots around the neck area. They possess a lengthy appendage which projects forward from the crown (Fig. 2). This feature is very rare among birds and is not the growth of a feather but a horny layer of skin continuous with the skull. This feature gives then the title “unicorn of the avian world”. The horned screamer supports itself with relatively long grey legs with three partially webbed toes. DISTRIBUTION. The horned screamer occurs in lowlands from Colombia and Ecuador to southern Brazil (Fig. 3). There used to be sightings in Trinidad, however they were on the verge UWI The Online Guide to the Animals of Trinidad and Tobago Ecology of extinction there in the 1930s, and there were no reports of sightings since 1964. Although they became extinct in Trinidad and Tobago, they remain common in other countries and there are reports that this species has been expanding in Brazil in recent years (Hilty, 2003). HABITAT AND ACTIVITY. The horned screamer inhabits well-vegetated wet tropical savannas, marshes, lakes in large open areas, forested areas and river banks (Fig.

Host list from Weller (1968), Höhn (1975), Lyon and Eadie 2013, Cabrera et al. 2017; see also Rees and Hillgarth (1984). Livzey (1986) presents waterfowl phylogeny showing Black-headed Duck to be sister- group to stiff-tails. Species known to have reared this brood parasite indicated by “%”. In captivity, reported hosts have included Rosy-billed Pochard Netta peposaca (Powell 1979, Rees and Hillgarth 1984), Red Shoveler Anas platalea (Todd 1979 1), and Common Moorhen Gallinula chloropus and Silver Teal Anas versicolor (Powell 1979 2. Rees and Hillgarth 1984). The Maguari Stork Ciconia maguari had been listed originally as a host based on supposed parasitic eggs which were later identified as being those of Rosy-billed Pochard Netta peposaca (see Weller 1968); subsequent records returns this species to this list of hosts (Cabrera et al. 2017).
