Cherrie's Tanager
Cherrie's tanager (''Ramphocelus passerinii costaricensis'') is a medium-sized passerine bird. This tanager is a resident breeder in the Pacific lowlands of Costa Rica and western Panama. This bird was formerly known as the scarlet-rumped tanager, but was split as a separate species from the Caribbean form, which was itself renamed as Passerini's tanager, ''Ramphocelus passerinii''. While most authorities had accepted this split, there were notable exceptions (e.g. the Howard and Moore checklist). It was lumped back into the Scarlet-rumped Tanager in 2018. Cherrie's tanager is very common from sea level to altitude, and occurs occasionally up to . The preferred habitat is semi-open areas including light second growth, woodland edges, gardens and pasture with bushes. The cup nest is built up to high in a tree. The normal clutch is two pale blue or grey eggs, marked with black, brown or lilac. This species will sometimes raise two broods in a season. The adult Cherrie's tanag ...

Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1891
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich.

Ramphocelus
''Ramphocelus'' is a Neotropical genus of birds of the tanager family. They have enlarged shiny whitish or bluish-grey lower mandibles, which are pointed upwards in display. However, this is greatly reduced in the females of most species. Males are black and red, orange or yellow, while females resemble a duller version of the males, or are brownish or greyish combined with dull red, orange or yellowish. ''Ramphocelus'' tanagers are found in semi-open areas. The nest is a cup built by the female of plant materials such as moss, rootlets, and strips of large leaves like banana or ''Heliconia'', and is often in a fairly open site in a tree. The female usually lays pale blue eggs, with grey, brown or lavender spots, and the young stay in the nest for only about 12 days. The songs of this genus are repetitions of rich one- or two-syllable whistles. ''Ramphocelus'' tanagers hunt at forest edges or in second growth, taking insects in flight or picking them from leaves.

Roosevelt River
The Roosevelt River (Rio Roosevelt, sometimes Rio Teodoro) is a Brazilian river, a tributary of the Aripuanã River about in length. Course The Roosevelt River begins in the state of Rondônia and flows north through tropical rainforest. It is fed by the Capitão Cardoso River, which meets it at the state boundary. In Mato Grosso the river forms the western boundary of the Guariba-Roosevelt Extractive Reserve, a sustainable use unit created in 1996. After entering Amazonas the river forms the border between the Manicoré State Forest, a sustainable use conservation unit created in 2005 and the Guariba State Park, also created in 2005. The river then runs through the Campos Amazônicos National Park, a protected area created in 2006 that holds an unusual enclave of cerrado vegetation in the Amazon rainforest. It continues north until it joins the Aripuanã River. The Aripuanã then flows into the Madeira River, thence into the Amazon. History and exploration Formerly ca ...

Theodore Roosevelt
Theodore Roosevelt Jr. ( ; October 27, 1858 – January 6, 1919), often referred to as Teddy or by his initials, T. R., was an American politician, statesman, soldier, conservationist, naturalist, historian, and writer who served as the 26th president of the United States from 1901 to 1909. He previously served as the 25th vice president of the United States, vice president under President William McKinley from March to September 1901 and as the 33rd governor of New York from 1899 to 1900.

George Cherrie
George Kruck Cherrie (August 22, 1865 – January 20, 1948) was an American naturalist and explorer. He collected numerous specimens on nearly forty expeditions that he joined for museums and several species have been named after him. Early life and education Cherrie was born in Knoxville, Iowa. When he was 12, he began working in saw mills before graduating from Iowa State College. He worked briefly at the college museum and then at Ward's Natural Science Establishment in Rochester, New York. Career He worked briefly at a Cedar Rapids electric bulb factory before shifting to natural history. Originally educated and employed as a mechanical engineer, he was unsatisfied and decided to study taxonomy and taxidermy instead. Cherrie then left the US and travelled to the West Indies and Central America. During the period 1889–1897, he was employed as a curator of birds at the Costa Rica National Museum in San José and the Field Museum in Chicago. Cherrie collected for the R ...

Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed-species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role.
