Foraging technique and prey-handling time in black-necked stork(Ephippiorhynchus asiaticus)

The foraging technique and prey-handling time of the black-necked stork(Ephippiorhynchus asiaticus)was stud-ied in Dudhwa National Park,India,from January 1996 to June 1997.The habitat in which the storks foraged played an important role in selecting a particular technique to procure food.Black-necked storks mostly foraged using a tactile technique(>90%),but sometimes foraged visually.When the water level was estimated to be less than 60 cm,the storks foraged using tactile techniques.There was no difference in the feeding techniques of male and female storks.Foraging attempt rates varied between the sexes in summer(May)and during late winter(February)in 1997.The search time for prey increased when the water level was high and fish were widely distributed.Decreases in water level resulted in concentration of fish in certain areas and this contributed to high fish-catching rates by black-necked storks.Males had a higher success rate of fish capture than females.However,females captured longer fish than males.Prey-handling time increased in both sexes as fish length increased.Fish 4–6 cm long were most frequently taken by the foraging storks.

怒江：一次偶然的发现 2014年的8月18日，怒江河谷里正值炎炎夏日，云南省怒江州泸水县六库镇石缸河村的青年冯清礼骑着摩托回家时，刚好路过自家村前的一条山沟，看见一个来自广西的矿工抓着一只自己从来没有见过的大鸟。平时冯清礼也爱好饲养些小动物，又觉得这只大鸟颇为新奇，于是和这名工人协商，花了数百元把这只大鸟买了过来。因为村里有人被聘为泸水县林业局的护林员，并给村民做过自然保护的宣教工作，使得冯清礼对野生动物保护的事情有一些意识。
