Abstract The author describes the presence of the oldest extinct diurnal birds of prey species in the world and fossilized representatives of different families, as well as the presence of recent species in the Carpathian Basin among fossilized remains. In case of ospreys, one of the oldest known materials is classified as a new extinct species named Pandion pannonicus. The text is supplemented by a plate and a size chart.

Raptors are some of the most at-risk groups of birds in the world and saving these top predators is essential for maintaining the health of many ecosystems. After hospitalization, raptors are often released when muscular recovery is still unfitting when they are unable to hunt efficiently and are at risk of dying from starvation within a few days. On the other hand, if a convalescent bird is trained with the only use of classic falconry techniques, it is likely to remain dependent on the caretaker/falconer even long after the release, so unable to hunt independently. To overcome these problems, a new training method was conceived, which could improve raptors’ muscular strength while limiting habituation to humans. This has been possible due to the combination of classic falconry techniques and modern technologies, such as the introduction of specific workouts with drones. Three falconry raptors and one wild Eurasian hobby were trained through high-tech falconry to develop the ability to catch, grasp, and airlift their prey at a different speed, altitude, and resistance. The main findings of this study were: (i) The rapid increase of the raptors’ speed; (ii) the muscular growth and endurance, and (iii) successful reintroduction of a wild bird.

The paper briefly discusses the most impressive examples of the Nikolai Vavilov’s “Law of homologous series” in the evolution of one of the largest animal groups, homopterous insects, which comprise about 65,000 recent species in the world fauna. Different taxonomic and phylogenetic characters (morpho-anatomical, cytogenetic, reproductive and others) are considered at the taxonomic ranks of the order, suborder, superfamily and family.

The Slender-billed Curlew (Numenius tenuirostris) is a very rare Palaearctic Scolopacidae, classified Critically Endangered by the IUCN, with the last accepted record in 2001. In the museum collections, it is commonly preserved with mounted specimens and study skins, but only two skeletons have been reported in the world. Here we present the re-preparation of a mounted specimen from the collection of the Museo di Zoologia of the Torino University in order to obtain as much osteological material as possible. This practice, especially with rare or extinct species, is recommended in different papers to maximize the value of the museum specimens and remedy the lack of skeletal elements of very rare or extinct species.

This article examines what is lost and remembered at a time of mass extinction; identifying the Anthropocene – the geological epoch in which the incremental and disruptive impact of the human species has become the main planetary force – as an epoch of mourning. The paper explores the memory and future memory of extinction through the example of Remembrance Day for Lost Species, an international initiative encouraging people all over the world to gather annually on 30th November in funeral ceremonies to mourn extinct species. The article particularly draws on Ursula Heise’s concept of ‘eco-cosmopolitanism’ (2008, 2016) and Michael Rothberg’s ‘multidirectional memory’ (2009) as well as fieldwork notes and interviews conducted during Lost Species Day 2018 in Brighton, UK. The analysis considers the conditions of future memory at a time of ecological loss by examining the extinction memorial and funerary practices formulated and performed during the Remembrance Day’s events.

Habitat Conversion

Summary Due to climate change and habitat conversion, estimates of the resulting levels of species extinction over the next century are alarming. Devising conservation solutions will require many different approaches, including examining the extinction processes of recently extinct species. Given that parrots are one of the most threatened groups of birds, information regarding parrot extinction is pressing. While most recent parrot extinctions have been island endemics, the Carolina Parakeet Conuropsis carolinensis had an 18th-century range covering nearly half of the present-day United States, yet mostly disappeared by the end of the 19th century. Despite a great deal of speculation, the major cause of its extinction remains unknown. Establishing the date when a species went extinct is one of the first steps in determining what caused their extinction. While there have been estimates of their extinction date, these analyses used a limited dataset and did not include observational data. We used a recently published, extensive dataset of Carolina Parakeet specimens and observations combined with a Bayesian extinction estimating model to determine the most likely extinction dates. By considering each of the two subspecies independently, we found that they went extinct ˜30 years apart: the western subspecies C. c. ludovicianus going extinct around 1914 and the eastern subspecies C. c. carolinensis either in the late 1930s or mid-1940s. Had we only considered all observations together, this pattern would have been obscured, possibly missing a major clue in solving the mystery of the parakeet’s extinction. Since the Carolina Parakeet was a wide-ranging species that went extinct during a period of rapid agricultural and industrial expansion, conditions that mirror those occurring in many parts of the world where parrot diversity is highest, any progress we make in unraveling the mystery of their disappearance may be vital to modern conservation efforts.
