Full Development

Ruffed grouse (Bonasa umbellus) were collected from August 26, 1965, to August 25, 1966, and examined for cestodes. Two morphological variations of Davainea tetraoensis were found, fully developed mature worms being recovered during the summer months and poorly developed winter forms with no mature prolottides being recovered during the winter months. Various causes are considered and investigated experimentally. Changes in diet and changes in photoperiodicity do not seem to effect any change from one form to the other; changes in temperature, however, seem to be closely related to the transition from summer forms to winter forms, this transition occurring at around 0C. The change back to mature forms may be linked to gonad development in the host or to those environmental factors which influence gonad development. Cysticercoids from experimentally infected molluscs are described and compared. The rate of development of cysticercoids in Zonitoides arboreus under different conditions is investigated showing that full development, from oncospheres, can occur within 12 days in small individuals (2 mm) but takes at least 19 days in larger individuals (4.5 mm). Examination of grouse and chickens after experimental infection with up to 450 cysticercoids showed no apparent ill effects, or damage of any kind, to the hosts.

Tanaisia zarudnyi occurs in the ureters and kidney tubules of ruffed grouse from Ontario and Michigan. The dark brown, operculate eggs are fully developed when oviposited. They remain viable for long periods of time at 2 to −15 °C and can withstand a temperature of −49 °C for 1 to 2 days. They hatch only when ingested by some mollusc. Development occurs in the digestive gland of the terrestrial snails Anguispira alternata and Succinea ovalis. Daughter sporocysts complete development in 6 weeks, by which time they contain undeveloped cercarial bodies. Within the next 2 weeks, most of the distomate. brevicercous cercariae are fully developed. The cercariae encyst within the daughter sporocyst, utilizing the contents of subcuticular glands to form the cyst. Encysted metacercariae are killed in the gizzard when fed to chickens, but excyst when inoculated directly into the duodenum. Excystation apparently results from secretions of the anterior glands of the stimulated metacercaria rather than from digestion of the cyst wall by the host. A 6-week-old ruffed grouse became infected when fed metacercariae, but 9 older ruffed grouse, 17 chickens, 4 white-throated sparrows, and 6 pheasants, fed similarly, were not infected. Apparently there is both host and age resistance to infection with this parasite.

The distribution and life cycle of a dicrocoeliid trematode, Brachylecithum orfi Kingston and Freeman, 1959, from the biliary ducts of the ruffed grouse, Bonasa umbellus, in Ontario and Michigan, have been studied in the definitive host and the intermediate molluscan hosts. Oval, dark brown, operculate eggs contain fully developed miracidia at oviposition. The eggs are coated with a lipid which prevents uptake of water and hatching until they are eaten by a mollusc; they will survive for more than 3 years at 2 °C and will tolerate exposure to −49 °C. The eggs hatch and larval stages develop in Zonitoides arboreus, Z. nitidus, Cionella lubrica, Deroceras laeve, and D. reticulatum, but not in 13 other species of terrestrial molluscs. Small, rounded, daughter sporocysts develop within the saclike mother sporocysts during the first 30 days after ingestion of eggs by suitable molluscs. Daughter sporocyst and cercarial development is completed 89–278 days after infection, depending on the species of mollusc and the temperature. The cercariae escape from the sporocyst endosac through a birth canal into the sinusoidal spaces of the mollusc. They migrate to the lung and out onto the dorsum of the mollusc via the respiratory pore, where they aggregate in numbers in slimeballs that are deposited on the substratum. Cercarial production continues for more than 100 days after onset. The longicercous, mesostomate xiphidiocercariae have a flame cell formula of 2((2 + 2 + 2) + (2 + 2 + 2)); they are provided with 6 preacetabular and 12 postacetabular glands, both groups of which open through pores lateral to the shank of the cercarial stylet. Cercariae in slime masses survive for 48 hours. When exposed to larval Colorado potato beetles, larval willow chrsyomelids, and mound-building ants, the cercariae penetrated the gut wall and encysted in the haemocoel, but died shortly afterwards.

Two morphologically distinct trypanosomes (Trypanosoma ontarioensis n.sp. and Trypanosoma paddae) were found by the haematocrit centrifuge technique in the blood of 53% (64 of 121) of Corvus brachyrhynchos brachyrhynchos wintering in southern Ontario. Trypanosoma ontarioensis n.sp. is a small trypanosome with subterminal kinetoplast. It is monomorphic and not host specific. It was readily cultured in diphasic blood-agar medium. Two-week cultures were infective and contained dividing sphaeromastigotes, epimastigotes, and trypomastigotes. Blood trypomastigotes were detected in low numbers in the blood of inoculated birds (Corvus brachyrhynchos brachyrhynchos, Bonasa umbellus, Gallus domesticus, Melopsittacus undulatus, and Serinus canarius) at 28 and 48 days postinfection. The crows, ruffed grouse, and domestic chicks were laboratory raised while the budgerigars and canaries were from pet stores. One canary that was further examined at 180, 360, 540, 730, and 910 days postinfection still had detectable numbers of trypanosomes in its blood.

The haemoproteids of the grouse family Tetraonidae are reviewed. Haemoproteus stableri n.sp. is described from the ruffed grouse, Bonasa umbellus, from Montana. Haemoproteus rotundus Oliger, 1956 and H. canachites Fallis and Bennett, 1960, are declared synonyms of Haemoproteus mansoni Castellani and Chalmers, 1910.

Specimens of Simulium aureum, S. latipes, S. venustum, and S. rugglesi feed on ruffed grouse although relatively few engorged specimens of the two latter species were obtained. S. aureum and S. latipes are suitable hosts for Leucocytozoon bonasae as shown by infections produced in grouse following injections of sporozoites removed from the salivary glands of these flies. The parasitaemia in grouse infected naturally and experimentally was relatively low and no gross signs of disease were noted in any of the infected birds.

Using infrared video-surveillance systems during 1999–2000, we observed attempts by two individual Long-tailed Weasels (Mustela frenata) to depredate female Ruffed Grouse (Bonasa umbellus) and their clutch of eggs. Neither female was captured despite Long-tailed Weasel attacks on multiple nights, but all eggs from one nest were either consumed or cached over a two-night period. Although Long-tailed Weasels have been shown to return quickly to areas of abundant prey, return visit behavior to locations where weasels were unsuccessful or only partially successful are poorly described.
