Bird fancier's lung.

Improved management of diabetic pregnancies at Lautoka Hospital, Fiji, in 1976 resulted in a neonatal survival rate of 100%. Management included attempts to control the maternal blood glucose concentrations with insulin and delaying delivery until there was enough surfactant in the liquor to ensure a viable infant. The techniques are simple to use and require only minimal technological facilities.

Randall, R. M. &; Randall, B. M. 1980. Status and distribution of the Roseate Tern in South Africa. Ostrich 51:14-20.

The Roseate Tern Sterna dougallii population in Algoa Bay is the largest, and now possibly the only breeding population in southern Africa. The two mainland breeding sites at Cape Recife and Kommetjie have been deserted, and in recent years the last remaining breeding site outside Algoa Bay may have been abandoned. Consequently the present estimate of between 70 and 80 breeding pairs in Algoa Bay may represent the entire southern African population. The decline in numbers from hundreds in 1937 is ascribed to human interference. Although the species is rare and endangered in southern Africa, it has a world wide distribution and is in no immediate danger of extinction.     

Bird song,ecology and speciation

The study of bird song dialects was once considered the most promising approach for investigating the role of behaviour in reproductive divergence and speciation. However, after a series of studies yielding conflicting results, research in the field slowed significantly. Recent findings, on how ecological factors may lead to divergence in both song and morphology, necessitate a re-examination. We focus primarily on species with learned song, examine conflicting results in the literature and propose some potential new directions for future studies. We believe an integrative approach, including an examination of the role of ecology in divergent selection, is essential for gaining insight into the role of song in the evolution of assortative mating. Habitat-dependent selection on both song and fitness-related characteristics can lead to parallel divergence in these traits. Song may, therefore, provide females with acoustic cues to find males that are most fit for a particular habitat. In analysing the role of song learning in reproductive divergence, we focus on post-dispersal plasticity in a conceptual framework. We argue that song learning may initially constrain reproductive divergence, while in the later stages of population divergence it may promote speciation.     

猛禽中的夜游者——鸮

“鸮”,就是我们俗称“猫头鹰”。人们对鸮都有一些简单的基本概念,一见到便能辨认出来。但是日常生活中我们却不容易见到它,因为鸮是一种食肉鸟类,在大自然中的密度原来就相当低,而且大多是昼伏夜出,加上动作敏捷而寂静,不易在野外觅得它的踪迹。自古以来,它们就是一种令人感到困惑而神秘的鸟类,既是智慧的象征,又被看作是死亡和厄运的征兆……那么鸮究竟是一种什么样的鸟类,人类是否真正地了解这种鸟呢？
