Turdoides Squamiceps
The Arabian babbler (''Argya squamiceps'') is a passerine bird until recently placed in the genus ''Turdoides''. It is a communally nesting resident bird of arid scrub in the Middle East which lives together in relatively stable groups with strict orders of rank. Taxonomy The Arabian babbler was formerly placed in the genus ''Turdoides'' but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus ''Argya''. The Leiothrichidae primarily occur in the Ethiopian and Oriental realms, but a few species in the genera ''Turdoides'' and ''Argya'' have penetrated into the Palearctic zone north of the tropics where they live in arid areas of North and East Africa, India and the Middle East. Description It is long with a wingspan of and a weight of . It has a fairly long curved bill, a long tail, rounded wings and strong legs and feet. The plumage is grey-brown above, paler below. There are dark streaks on the back and the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of The Middle East
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have furth ...

Gecko
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the brille. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick their own brilles whe ...

Arthropods
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...

Max Planck Institute For Ornithology
The Max Planck Institute for Ornithology (, abbreviated MPIO) was a non-university research institution under the sponsorship of the Max Planck Society. As of 1 January 2023, it merged with the Max Planck Institute for Neurobiology (MPIN) to form the new Max Planck Institute for Biological Intelligence (MPI-BI). The MPIO was located in Seewiesen, which belongs to the municipality of Pöcking in Upper Bavaria. The institutes’s focus was on basic scientific research in the fields of organismic biology, zoology, ornithology, neurobiology, behavioural ecology, evolutionary biology and evolutionary genetics. The institute is managed on a collegial basis, i.e. one of the two directors of the institute takes over the management for a certain time period. The last managing director was Manfred Gahr (2020–2022). History and current developments The Max Planck Institute for Behavioural Physiology was inaugurated in Seewiesen in 1958 under the direction of Erich von Holst and the ...

Handicap Principle
The handicap principle is a hypothesis proposed by the Israeli biologist Amotz Zahavi in 1975. It is meant to explain how "signal selection" during mate choice may lead to Signalling theory, "honest" or reliable signalling between male and female animals which have an obvious motivation to bluff or deceive each other. The handicap principle suggests that secondary sexual characteristics are costly signals which must be reliable, as they cost the signaller resources that individuals with less of a particular trait could not afford. The handicap principle further proposes that animals of greater fitness (biology), biological fitness signal this through handicapping ethology, behaviour, or Morphology (biology), morphology that effectively lowers overall fitness. The central idea is that sexually selected traits function like conspicuous consumption, signalling the ability to afford to squander a resource. Receivers then know that the signal indicates quality, because inferior-quality ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amotz Zahavi
Amotz Zahavi (; August 14, 1928 – May 12, 2017) was an Israeli evolutionary biologist, a Professor in the Department of Zoology at Tel Aviv University, and one of the founders of the Society for the Protection of Nature in Israel. His main work concerned the evolution of signals, particularly those signals that are indicative of fitness, and their selection for "honesty". Biography Amotz Zahavi was influenced to study zoology by the director of the zoo at Tel Aviv, Heinrich Mendelssohn. He received his Ph.D. from Tel Aviv University in 1970. He was married to Avishag Zahavi, a biologist and a co-investigator. He died in Tel Aviv, Israel on May 12, 2017, aged 88. Scientific career Zahavi is best known for his work on the handicap principle, which explains the evolution of characteristics, behaviors or structures that appear contrary to the principles of Darwinian evolution in that they appear to reduce fitness and endanger individual organisms. Evolved by sexual selection, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altruism In Animals
In biology, altruism refers to behaviour by an individual that increases the fitness (biology), fitness of another individual while decreasing their own. Altruism in this sense is different from the philosophical concept of altruism, in which an action would only be called "altruistic" if it was done with the conscious intention of helping another. In the behavioural sense, there is no such requirement. As such, it is not evaluated in moral terms—it is the consequences of an action for reproductive fitness that determine whether the action is considered altruistic, not the intentions, if any, with which the action is performed. The term ''altruism'' was coined by the French philosopher Auguste Comte in French, as ''altruisme'', for an antonym of egoism. He derived it from the Italian ''altrui'', which in turn was derived from Latin ''alteri'', meaning "other people" or "somebody else". Altruistic behaviours appear most obviously in Kin selection, kin relationships, such as in p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethology
Ethology is a branch of zoology that studies the behavior, behaviour of non-human animals. It has its scientific roots in the work of Charles Darwin and of American and German ornithology, ornithologists of the late 19th and early 20th century, including Charles Otis Whitman, Charles O. Whitman, Oskar Heinroth, and Wallace Craig. The modern discipline of ethology is generally considered to have begun during the 1930s with the work of the Dutch biologist Nikolaas Tinbergen and the Austrian biologists Konrad Lorenz and Karl von Frisch, the three winners of the 1973 Nobel Prize in Physiology or Medicine. Ethology combines laboratory and field science, with a strong relation to neuroanatomy, ecology, and evolutionary biology. Etymology The modern term ''ethology'' derives from the Greek language: wikt:ἦθος, ἦθος, ''ethos'' meaning "character" and , ''wikt:-logia, -logia'' meaning "the study of". The term was first popularized by the American entomologist William Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
