붉은머리오목눈이 또는 뱁새(문화어: 부비새, 비비새)는 한반도와 동남아시아에 서식하는 연작류이다.
둥지
둥지는 개나리, 국수나무, 찔레나무, 쥐똥나무, 사철나무, 조릿대 등의 키가 작은 나무에 지푸라기와 죽은 잡목의 나무 껍질들을 거미줄로 연결해서 밥그릇 모양으로 만든다. 붉은머리오목눈이의 둥지는 비바람에 무너지지 않을 만큼 튼튼하다. 덤불숲에 있어서 비에 둥지가 완전히 젖지 않으며, 보통 4~6개의 알을 낳아 번식한다.
붉은머리오목눈이의 천적은 둥지를 빼앗는 뻐꾸기, 그리고 알을 먹는 어치 · 누룩뱀 등이 있다.
알
전 세계적으로 둥지마다 푸른색과 하얀색이 있는데, 이와 전혀 다른 색의 알을 낳는 새는 드물다. 색깔은 암컷의 유전자에 따라 정해진다. 하얀색의 알을 낳는 암컷은 계속 하얀 알을 낳고, 푸른색의 알을 낳는 암컷은 푸른 알을 낳는 것이다. 하얀 알과 푸른 알의 비율은 지역에 따라 조금씩 차이가 있지만 보통 70~80%가 푸른색 알을 낳는다.
특징
붉은머리오목눈이는 비교적 작고 꼬리가 긴 새이다. 몸길이는 11내지 12.5cm 사이이다. 체중은 성별에 따라 약간 다르며, 수컷의 몸무게는 8.5~11g이고 암컷의 몸무게는 7~12g이다.

Habitat and movements
The vinous-throated parrotbill occurs from northern Vietnam to southern Manchuria, and occupies a wide range of habitats across its range. It is generally found in somewhat open wooded habitats, including scrub, woodland of early successional to late mature secondary stages, forest edges, thickets and bamboo stands. It also occurs in hedges, reeds and marshes. They also will adapt to human modified habitats such as tea plantations and plant nurseries. In China it is found in lower montane areas. In Sichuan it is replaced at 1,000 m (3,300 ft) above sea level by the ashy-throated parrotbill, whereas in Taiwan, where it is the only species of parrotbill, it occurs from sea level to 3,100 m (10,200 ft) and occupies the widest niche of any bird on that island.[5]
Description
The vinous-throated parrotbill is a relatively small and long-tailed parrotbill. It measures between 11 and 12.5 cm (4.3–4.9 in) in length. The weight varies slightly by sex, with males weighing between 8.5 to 11 g (0.30–0.39 oz) and the females weighing 7 to 12 g (0.25–0.42 oz)[verification needed]. The tail is graduated and like other parrotbills the bill is short and has the nostrils concealed by feather bristles. The plumage is similar for both sexes, which in the nominate is warm brown on the upperparts, dark brown on the wings (tinged with chestnut on the flight feathers). The upper breast and throat are pinkish-cream with brown streaks on the throat. The flanks are similar to the upperparts but slightly buffy, and the belly is cream-buff merging into the breast. The crown and forehead are rufescent brown, with a pale grey iris and the bill is either slate grey or brown with a paler or yellow tip.
Behaviour
Like other parrotbills and indeed related babblers, the vinous-throated parrotbill is a highly social species, usually encountered in groups. These flocks vary in size through the year, being at their smallest during the breeding season and increasing to as many as 140 individual birds in the winter. The members of winter flocks in Taiwan were described by a study as having four categories of member: core members, which never left the flock; regular members, which generally stayed in the flock but visited or briefly joined other flocks; floaters, which moved around between flocks; and peripheral members, which were only seen for less than two months and were assumed to be visitors from other areas. The ranges of large winter flocks can overlap with that of other flocks and flocks passing close together retain their cohesion.
