  • Some Parasites of the Common Crow, Corvus Brachyrhynchos Brehm, from Ohio1' 2
    SOME PARASITES OF THE COMMON CROW, CORVUS BRACHYRHYNCHOS BREHM, FROM OHIO1' 2 JOSEPH JONES, JR. Biology Department, Saint Augustine's College, Raleigh, North Carolina ABSTRACT Thirty-one species of parasites were taken from 339 common crows over a twenty- month period in Ohio. Of these, nine are new host records: the cestodes Orthoskrjabinia rostellata and Hymenolepis serpentulus; the nematodes Physocephalus sexalatus, Splendido- filaria quiscali, and Splendidofilaria flexivaginalis; and the arachnids Laminosioptes hymenop- terus, Syringophilus bipectinatus, Analges corvinus, and Gabucinia delibata. Twelve parasites not previously reported from the crow in Ohio were also recognized. Two tables, one showing the incidence and intensity of parasitism in the common crow in Ohio, the other listing previous published and unpublished records of common crow parasites, are included. INTRODUCTION Although the crow is of common and widespread occurrence east of the Rockies, no comprehensive, year-round study of parasitism in this bird has been reported. Surveys of parasites of common crows, collected for the most part during the winter season, have been made by Ward (1934), Morgan and Waller (1941), and Daly (1959). In addition, records of parasitism in the common crow, reported as a part of general surveys of bird parasites, are included in publications by Ransom (1909), Mayhew (1925), Cram (1927), Canavan (1929), Rankin (1946), Denton and Byrd (1951), Mawson (1956; 1957), Robinson (1954; 1955). This paper contains the results of a two-year study made in Ohio, during which 339 crows were examined for internal and external parasites. MATERIALS AND METHODS Juvenile and adult crows were shot in the field and wrapped individually in paper bags prior to transportation to the laboratory.

A check list of the helminths of guineafowls (Numididae) and a host list of these parasites. Onderstepoort Journal of Veterinary Research, 74:315–337 Published and personal records have been compiled into a reference list of the helminth parasites of guineafowls. Where data on other avian hosts was available these have been included for complete- ness’ sake and to give an indication of host range. The parasite list for the Helmeted guineafowls, Numida meleagris, includes five species of acanthocephalans, all belonging to a single genus, three trematodes belonging to three different genera, 34 cestodes representing 15 genera, and 35 nema- todes belonging to 17 genera. The list for the Crested guineafowls, Guttera edouardi, contains a sin- gle acanthocephalan together with 10 cestode species belonging to seven genera, and three nema- tode species belonging to three different genera. Records for two cestode species from genera and two nematode species belonging to a single genus have been found for the guineafowl genus Acryllium. Of the 70 helminths listed for N. meleagris, 29 have been recorded from domestic chick- ens.

    A NEW ACANTHOCEPHALAN FROM AN EAST AFRICAN GALLIFORM BIRD By M. T. HARRIS CONTENTS Page Synopsis . 455 Introduction . 455 Description 455 Discussion 458 Acknowledgements 459 References 459 I. SYNOPSIS A new species of acanthocephalan, Mediorhynchus selengensis, is described from the yellow- necked spurfowl {Pternistes leucoscepus) in Kenya, and its relationship to other species of Mediorhynchus discussed. A brief discussion on the relationship between the genera Empodius, Empodisma and Mediorhynchus is also given. 2. INTRODUCTION The worms to be described in this paper were amongst a collection of helminths submitted for identification by Mr. John E. Cooper of the Veterinary Research Laboratory, Kabete, Kenya. Thirty-two specimens were obtained from the intestine of yellow-necked spurfowl {Pternistes leucoscepus) at Selengai in Kenya. The worms belong to the family Gigantorhynchidae Hamann, 1892, the members of which occur in birds and mammals. 3. DESCRIPTION Mediorhynchus selengensis, sp. n. (Figs 1-4) The male worm measures 11 •6-43-0 mm in length and 0-80-2 -24 mm in maximum width; females, 11-3-91 -5 mm and 0-70-2-75 mm, respectively. The body is fairly long, pseudosegmented in mature specimens, with the anterior portion slightly thinner than the remainder of the body. The proboscis is cylindrical and composed of an anterior region bearing hooks and a posterior part armed with spines (fig. i). It was found extruded in only 7 of the specimens, and in these it measures 0-41-0-86 mm in length and 0-35-0-59 mm wide at the base. The hooks are stout and strong with a sharply-curved point, those on the anterior surface of the proboscis being shghtly smaller than the remainder (fig.

Nickol Deportment of Zoology, The University of Nebraska, Lincoln, Nebraska 68508 ABSTRACT: One hundred eighty-three woodpeckers of eight species collected in Louisiana were exam­ ined for Acanthocephala. Only the red-bellied woodpecker, Centurus carolinus, was infected. One of 53 was parasitized by an irrunature specimen of Mediorhynchus grandis; three by Centrorhynchus spinosus; 12 by Mediorhynchus centurorum sp. n. The new species of Mediorhynchus is distinguished by a trunk which is very narrow in the anterior 3 mm, but is suddenly expanded farther posteriad.

  • Some Internal and External Parasites of the Redwinged Blackbird
    THE OHIO JOURNAL OF SCIENCE VOL. 65 MARCH, 1965 No. 2 SOME INTERNAL AND EXTERNAL PARASITES OF THE REDWINGED BLACKBIRD, AGELAIUS PHOENTCEUS PHOENICEUS L., FROM CENTRAL OHIO; INCLUDING DESCRIPTIONS OF THREE NEW FEATHER MITES1- 2 GERHARD R. SPORY Department of Zoology and Entomology, The Ohio State University, Columbus 103 ABSTRACT From sixty-one redwinged blackbirds that were collected and examined between 1962 and 1963, eighteen species of parasites were recovered. Seven species of parasites represent new host records. These are: the trematode Conspicuum icteridorum; the feather mites Strelkoviacarus critesi sp. n., Mesalges johnstoni sp. n., Proctophyllodes egglestoni sp. n., Dermoglyphus sp.; the nasal mite Speleognathus sp.; and the mallophagan Machaerilaemus laticorpus. Cited is a table containing previous published and unpublished records of parasites taken from redwinged blackbirds. During the summer and autumn of 1962 and spring of 1963 a study was made of the internal and external parasites of the redwinged blackbird, Agelaius p. phoeniceus, from central Ohio. Sixty-one birds were collected from The Ohio State University farm pond area in Franklin County, Ohio, and the Delaware Reservoir Wildlife Area, Delaware County, Ohio. The procedure used in capturing redwings and collecting their parasites can be found in my Master's thesis (Spory, 1963). The following list presents the parasites found in this study, including descrip- tions for three new feather mites. Acanthocephala Order Archiacanthocephala Family Gigantorhynchus Mediorhynchus grandis Van Cleave, 1916. A single worm was found in the intestine of each of two birds of the 61 examined. Other hosts for this parasite have been reported by Van Cleave (1947).
