Vulture
Offers an enlightening new history of this much-misunderstood bird. Vultures vary in type and size, and while some have a diet mainly of bone, others are actually almost completely vegetarian. Most interesting, despite its notorious association with death, the vulture very rarely, if ever, kills for itself. Van Dooren explores many histories, from some of the earliest-known Neolithic sites in which vultures are thought to have consumed the dead to contemporary efforts to reintroduce the bearded vulture into the Alps. Highlighting the rich diversity of vultures and the many ways in which people have understood and lived with them, this book invites a new appreciation and wonder for these incredible birds.

Vultures of the World
In Vultures of the
World , Keith L. Bildstein provides an
engaging look at vultures and condors, seeking to help us
understand these widely recognized but underappreciated
birds.
Bildstein's latest work is an inspirational and long overdue
blend of all things vulture. Based on decades of personal
experience, dozens of case studies, and numerous up-to-date
examples of cutting-edge science, this book introduces readers to
the essential nature of vultures and condors. Not only do these
most proficient of all vertebrate scavengers clean up natural and
man-made organic waste but they also recycle ecologically essential
elements back into both wild and human landscapes, allowing our
ecosystems to function successfully across generations of
organisms. With distributions ranging over more than three-quarters
of all land on five continents, the world's twenty-three species of
scavenging birds of prey offer an outstanding example of biological
diversity writ large.
Included in the world's species fold are its most abundant large
raptors-several of its longest lived birds and the most massive of
all soaring birds. With a fossil record dating back more than fifty
million years, vultures and condors possess numerous adaptions that
characteristically serve them well but at times also make them
particularly vulnerable to human actions. Vultures of the
World is a truly global treatment of vultures, offering a
roadmap of how best to protect these birds and their important
ecology.

A Late Miocene Accipitrid
Old World vultures are likely polyphyletic, representing two subfamilies, the Aegypiinae and Gypaetinae, and some genera of the latter may be of independent origin. Evidence concerning the origin, as well as the timing of the divergence of each subfamily and even genera of the Gypaetinae has been elusive. Compared with the Old World, the New World has an unexpectedly diverse and rich fossil component of Old World vultures. Here we describe a new accipitriform bird, Anchigyps voorhiesi gen. et sp. nov., from the Ash Hollow Formation (Upper Clarendonian, Late Miocene) of Nebraska. It represents a form close in morphology to the Old World vultures. Characteristics of its wing bones suggest it was less specialized for soaring than modern vultures. It was likely an opportunistic predator or scavenger having a grasping foot and a mandible morphologically similar to modern carrion-feeding birds. The new fossil reported here is intermediate in morphology between the bulk of accipitrids and the Old World gypaetine vultures, representing a basal lineage of Accipitridae trending towards the vulturine habit, and of its Late Miocene age suggests the divergence of true gypaetine vultures, may have occurred during or slightly before the Miocene.

Foraging shifts in a Neotropical Turkey Vulture
Intraspecific competition is believed to play a pivotal role in shaping the structure and resource use of migrant and resident bird communities. We compared seasonal movements and apparent survival of patagially-markcd and radio-tagged individuals of a Neotropical subspecies of Turkey Vulture (Cathartes aura ruficollis) in central Venezuela in relation to the presence and absence of a larger, dominant, northern subspecies, C. a. meridionalis. We found that the ruficollis population was partially migratory during the periods when migrants arrived and departed. Tagged individuals used areas with higher and lower proportional forest and semi-open vegetation types, respectively, during the dry season than wet season months to avoid competition with migrants. Moreover, apparent survival of ruficollis was lower during sympatry than allopatry. Our study provided evidence that C. a. meridionalis competed with C. a. ruficollis during their tropical residence period, supporting the hypothesis that intraspecific competition contributes to niche separation between these subspecies.

This is a call : the life and times of Dave Grohl
The epic story of a singular career that includes Nirvana, Foo Fighters, Queens of the Stone Age, and Them Crooked Vultures. Based on ten years of original, exclusive interviews with the man himself and conversations with a legion of musical associates like Queens of the Stone Age frontman Josh Homme, DC punk legend Ian MacKaye, and Nevermind producer Butch Vig, this is Grohl's story. He speaks candidly and honestly about Kurt Cobain, the arguments that almost tore Nirvana apart, the feuds that threatened to derail the Foo Fighters' global success, and the dark days that almost caused him to quit music for good.

A broad range of physical lesions and mortalities in scavenger raptors of Patagonia/Una amplia variedad de lesiones fisicas y mortalidades en rapaces carroneras en la Patagonia
The avian scavenger raptors guild of Patagonia, the southernmost region of South America (3756[degrees]S), comprises 3 species of obligate scavengers and 7 species of facultative scavengers. Despite the species richness, there is little information about the anthropogenic threats this guild might face. Here, based on 164 h of observations and photographic records across 3 austral winters, we reveal a broad range of lesions (missing legs, digits or talons, fractures, luxations, pododermatitis, necrosis, hyperkeratosis, and beak and ocular lesions) and mortalities among scavenger raptors in Argentine Patagonia at 2 anthropogenic food-rich sites located 1,750 km apart at 38[degrees] and 54[degrees] S. Wc photographed 146 individuals with 174 physical lesions and found 61 dead individuals, including one obligate scavenger species (Black Vulture, Coragyps atratus) and 4 facultative scavenger species (Crested Carneara, Caracara plancus; Chimango Caracara, Daptrius chimango; White-throated Caracara, D. albogularis; and Black-chested Buzzard-Eagle, Geranoaetus melanoleucus). Ninety percent of the lesions we recorded on the individuals were located on their hindlimbs. None of the carcasses we found exhibited any apparent lesions. The precise nature and origins of these lesions and mortalities remain uncertain. However, the hindlimb lesions align with the effects of leg-hold traps, while poisoning emerges as the most likely cause of mortality among individuals foraging at these anthropogenic food-rich sites. These findings suggest a notable human-induced threat to the avian scavenger raptors guild in Patagonia. Received 3 February 2024. Accepted 19 June 2024.
