Jane



Jane is a feminine given name. It is the English form of the Old French name Jehanne, which was an old feminine form of the male name Johannes or Ioannes, a Latin form of the Greek name ωάννης, which is derived from the Hebrew name יוֹחָנָן, a short form of the name יְהוֹחָנָן, meaning "Yahweh is merciful". The name was first used in large numbers in the mid-16th century for the daughters of aristocrats as an alternative to the more commonplace Joan. The two names have alternated popularity. In the early 19th century, Jane was again seen as a name with a certain amount of glamour. Joan became more popular in the early to mid-20th century, when it was ranked in the top 500 most popular names given to girls in the United States, but the name has again been displaced by Jane on the popularity charts in the 21st century.

Eastern Meadowlark


The adult Eastern meadowlark measures from 19 to 28 cm (7.5 to 11 in) in length and spans 35–40 cm (14–16 in) across the wings.[2] Body mass ranges from 76 to 150 g (2.7 to 5.3 oz).[3][4] The extended wing bone measures 8.9–12.9 cm (3.5–5.1 in), the tail measures 5.3–8.6 cm (2.1–3.4 in), the culmen measures 2.8–3.7 cm (1.1–1.5 in) and the tarsus measures 3.6–4.7 cm (1.4–1.9 in). Females are smaller in all physicial dimensions.[5] Adults have yellow underparts with a black "V" on the breast and white flanks with black streaks. The upperparts are mainly brown with black streaks. They have a long pointed bill; the head is striped with light brown and black.

The song of this bird is of pure, melancholy whistles, and thus simpler than the jumbled and flutey song of the Western Meadowlark; their ranges overlap across central North America. In the field, the song is often the easiest way to tell the two species apart, though plumage differences do exist, like tail pattern and malar coloration.

The pale Lilian's Meadowlark of northern Mexico and the southwestern US is sometimes split off as a separate species.

Chinese Pond Heron


The Chinese Pond Heron (Ardeola bacchus) is an East Asian freshwater bird of the heron family (Ardeidae).
It is one of six species of birds known as "pond herons" (genus Ardeola). It is parapatric (or nearly so) with the Indian Pond Heron (A. grayii) to the west and the Javan Pond Heron (A. speciosa) to the south, and these three are presumed to form a superspecies. As a group they are variously affiliated with the Squacco Heron (A. grayii) or the Madagascar Pond Heron (A. idae). As of mid-2011 there are no published molecular analyses of pond heron interrelationships and osteological data is likewise not analyzed for all relevant comparison taxa.
