Magpie Jay General Information and Care
Magpie Jay General Information and Care: Black Throated Magpie Jays (Calocitta colliei) and White Throated Magpie Jay (Calocitta formosa) are the only two species in their genus. Black Throated Magpie Jays are endemic to Northwestern Mexico. The range of White Throated Magpie Jays lies to the south, overlapping with Black Throats slightly in the Mexican states of Jalisco and Colima, and running into Costa Rica. Both of these birds are members of the family Corvidae. Magpie Jays are energetic, highly intelligent animals and need to be kept in a large planted aviary - not just a cage. These birds are highly social and are commonly found in the wild as cooperative nesters. They are omnivores and favor a great variety of fruits, insects, small rodents, and nuts. A captive diet that works well in my aviaries is a basic pellet low iron softbill diet such as Kaytee’s Exact Original Low Iron Maintenance Formula for Toucans, Mynas and other Softbills. A bowl of this is in the cage at all times and is supplemented with nuts, fruits and veggies like apples, papaya, grapes, oranges, peas and carrots and the occasional treat of small mice and insects like meal worms, crickets, megaworms, and waxworms are relished by the birds. Extra protein is essential if you want these birds to breed. Fresh water should always be provided. I use a shallow three to four inch deep, twelve inch wide crock the birds can drink from and bath in. The birds you are receiving from my aviaries are hand fed and closed banded. How recently they were weaned will affect how tame they are at first. -

A Bird in Our Hand: Weighing Uncertainty About the Past Against Uncertainty About the Future in Channel Islands National Park
A Bird in Our Hand: Weighing Uncertainty about the Past against Uncertainty about the Future in Channel Islands National Park Scott A. Morrison Introduction Climate change threatens many species and ecosystems. It also challenges managers of protected areas to adapt traditional approaches for setting conservation goals, and the phil- osophical and policy framework they use to guide management decisions (Cole and Yung 2010). A growing literature discusses methods for structuring management decisions in the face of climate-related uncertainty and risk (e.g., Polasky et al. 2011). It is often unclear, how- ever, when managers should undertake such explicit decision-making processes. Given that not making a decision is actually a decision with potentially important implications, what should trigger management decision-making when threats are foreseeable but not yet mani- fest? Conservation planning for the island scrub-jay (Aphelocoma insularis) may warrant a near-term decision about non-traditional management interventions, and so presents a rare, specific case study in how managers assess uncertainty, risk, and urgency in the context of climate change. The jay is restricted to Santa Cruz Island, one of the five islands within Chan- nel Islands National Park (CINP) off the coast of southern California, USA. The species also once occurred on neighboring islands, though it is not known when or why those populations went extinct. The population currently appears to be stable, but concerns about long-term viability of jays on Santa Cruz Island have raised the question of whether a population of jays should be re-established on one of those neighboring islands, Santa Rosa. -

Accepted on 29 December 2015. ABstract: Corvids are renowned for their variable foraging behaviour, and about 20 species in eight genera perch on wild and domestic ungulates to pick ticks on the body of these mammals. Herein I illustrate and briefly comment on the Purplish Jay (Cyanocorax cyanomelas) riding deer and tapir in the Pantanal, Western Brazil. The jay perched on the head or back of the ungulates and searched for ticks, playing the role of a cleaner bird. Deer are rarely reported as hosts or clients of tick-picking birds in the Neotropics. The Purplish Jay is the southernmost Neotropical cleaner corvid reported to date. Given their opportunistic foraging behaviour, a few other Cyanocorax jay species may occasionally play the cleaner role of wild and domestic ungulates. KEY-WORDS: Cyanocorax cyanomelas, foraging, cleaning behaviour, Pantanal, Western Brazil. -

The Puzzling Vocal Repertoire of the South American Collared Jay, Cyanolyca Iridicyana Merida
THE PUZZLING VOCAL REPERTOIRE OF THE SOUTH AMERICAN COLLARED JAY, CYANOLYCA VZRIDZCYANA MERIDA JOHN WILLIAM HARDY Previously, I have indicated (Kansas Sci. Bull., 42: 113, 1961) that the New World jays could be systematically grouped in two tribes on the basis of a variety of morphological and behavioral characteristics. I subsequently demonstrated (Occas. Papers Adams Ctr. Ecol. Studies, No. 11, 1964) the relationships between Cyanolyca and Aphelocoma. The tribe Aphelocomini, comprising the currently recognized genera Aphelocoma and Cyanolyca, may be characterized as follows: pattern and ornamen- tation of head simple, consisting of a dark mask, pale superciliary lineation, and no tendency for a crest; tail plain-tipped; vocal repertoire of one to three basic com- ponents, including alarm calls, flock-social calls, or both, that are nasal, querulous, and upwardly or doubly inflected. In contrast, the Cyanocoracini may be charac- tized as follows: pattern of head complex, consisting of triangular cheek patch, super- ciliary spot, and tendency for a crest; tail usually pale-tipped; vocal repertoire usu- ally complex, commonly including a downwardly inflected cuwing call and never an upwardly inflected, nasal querulous call (when repertoire is limited it almost always includes the cazo!ingcall). None of the four Mexican aphelocomine jays has more than three basic calls in its vocal repertoire. There are two exclusively South American species of CyanuZyca (C. viridicyana and C. pulchra). On the basis of the consistency with which the Mexican and Central American speciesof this genus hew to a general pattern of vocalizations as I described it for the tribe, I inferred (1964 op. -

Jeremy Minns' Site Notes
Jeremy Minns‘ Site Notes ACRE In 1999 I spent three weeks at the Reserva Extrativista do Alto Juruá, a reserve on the Rio Juruá near the border with Peru. The original inhabitants are allowed to farm and hunt for their own use and the forest and wild life is practically intact. Access is by light aircraft or boat only and one needs to mount an expedition to penetrate the region as there are no roads or shops. Birding is magnificent – we had almost 400 species. Many of these however can be seen more easily in Peru at Manu. Permission to enter the reserve must be obtained from IBAMA and the Rubber Tappers‘ Union in Cruzeiro do Sul. I know there is plenty of forest with good birding accessible by car from Cruzeiro do Sul but I have had no personal experience with this. ALAGOAS Murici The best but most expensive place to stay is the Quilombo Parque hotel in União dos Palmares. It is pleasantly situated with plenty of birds in the grounds, including Seven- colored tanager Tangara fastuosa. It takes at least 50 minutes to get to the reserve from the hotel. The road to the IBAMA reserve, near Fazenda Bananeiras, is very bad and you will need four-wheel drive if there has been any rain. Take a dirt road to the right off the BR-104 (signposted Fazenda Serra Nova), 700m north of the entrance to Murici. The way is complicated, with many tracks to the right and left. Keep to the ―main‖ road. At a T junction with another ―main‖ dirt road, turn left. -
The White-Throated Magpie-Jay
THE WHITE-THROATED MAGPIE-JAY BY ALEXANDER F. SKUTCH ORE than 15 years have passed since I was last in the haunts of the M White-throated Magpie-Jay (Calocitta formosa) . During the years when I travelled more widely through Central America I saw much of this bird, and learned enough of its habits to convince me that it would well repay a thorough study. Since it now appears unlikely that I shall make this study myself, I wish to put on record such information as I gleaned, in the hope that these fragmentary notes will stimulate some other bird- watcher to give this jay the attention it deserves. A big, long-tailed bird about 20 inches in length, with blue and white plumage and a high, loosely waving crest of recurved black feathers, the White-throated Magpie-Jay is a handsome species unlikely to be confused with any other member of the family. Its upper parts, including the wings and most of the tail, are blue or blue-gray with a tinge of lavender. The sides of the head and all the under plumage are white, and the outer feathers of the strongly graduated tail are white on the terminal half. A narrow black collar crosses the breast and extends half-way up each side of the neck, between the white and the blue. The stout bill and the legs and feet are black. The sexes are alike in appearance. The species extends from the Mexican states of Colima and Puebla to northwestern Costa Rica. A bird of the drier regions, it is found chiefly along the Pacific coast from Mexico southward as far as the Gulf of Nicoya in Costa Rica. -
