四只在2014年 10月份被置上卫星追踪器的大滨鹬,刚刚开展了牠们今季的迁徙之旅!

It is very exciting that four great knots equipped with satellite tags since October 2014 have decided to migrate!

 

虽然现在仍是迁徙季节的开始,第一批大滨鹬已经在3月20日的傍晚从澳大利亚的罗巴克海湾出发,当中包括了我们其中一只进行卫星追踪的个体。在23及24日再有叁只卫星追踪的大滨鹬开始迁徙。

It is still early in the migration season, and the first flock reported to leave Roebuck Bay did so on 20 March. One of our satellite-tagged birds must have been among them that evening. The other three left on 23rd and 24th March.

定位数据显示我们追踪的第一只鸟已经在3月25日抵达了南海区域, 并在广东省的汕尾停留。

Our first bird reached the South China Sea on 25th March, landed at Shanwei in Guangdong Province.

虽然卫星定位的数据能够记录雀鸟个体的所在位置,但仍不能为我们提供当时实际环境情况的资料,因此任何环誌标记雀鸟个体的野外目击记录对我们的研究工作都十分有用。如果你们在野外发现有环誌标记的雀鸟个体,请将牠们脚上环誌的颜色组合(详情见下),以及目击的日期时间记下。同时,牠们的行为(如觅食、歇息等),所在地雀群的数量,牠们在使用的生境(如泥滩、渔塘等),以及雀鸟和生境的照片等这些额外的讯息,都能帮助我们更加了解牠们的迁徙行为。我们收集记录的邮箱是ysshorebird@gmail.com。

Any observations of the tagged birds will be extremely helpful to our research, because the location we got does not inform us about the actual environment where the bird is. Therefore we hope you can record the colour-ring combination of the bird (see below for further explanation), and time and date of your observation. More information, such as its behaviour (e.g. foraging, resting), the number of birds in the same area, the kind of environment it was in (e.g. mudflat, fishpond), and photos of the bird and its environment will be very helpful. Please email sightings to us by ysshorebird@gmail.com.

 

我们利用独特的颜色组合来标置不同环誌个体,每一只鸟的双脚上共有四个环誌以及一个旗标,分别有四种颜色:红 、黄、青、蓝。黄色的旗标代表牠们是在西北澳大利亚被放上标誌的。分辨雀鸟个体的关键便是将四个环誌和旗标的颜色组合和位置记录下来。

以下是第一只离开澳西北的装了卫星追踪器的大滨鹬!牠的脚环组合是:

左脚(由上至下):红环、黄旗、黄环
右脚(由上至下):青环、红环

We used unique colour-ring combination to mark individual birds - on each bird there are four rings and one flag. There are four colours used: Red, Yellow, Lime and Blue. There is also a yellow flag which represents Northwest Australia. It is very important to record the colour and position of the flag and each of the four rings. To illustrate, here is the first bird migrated! Its combination is

Left leg (from top to bottom): Red ring, yellow flag, yellow ring.

Right leg (from top to bottom): Lime ring, red ring.
