The first species to generate a lot of interesting information was frogs.

第一种产生很多有趣的信息是青蛙。

And there was a clear pattern here - they proliferate where there is suitable water.

这有一个清晰的模式，哪里有恰当的水源，它们就在那里增殖。

Garden ponds are on the increase, rural ponds are disappearing, leading to massive migration to the towns.

花园池塘在增加，而农村的池塘正在消失，导致大规模的迁移到城镇。

Hedgehogs are also finding it easier to live in urban areas - this time because their predators are not finding it quite so attractive to leave their rural environment, so hedgehogs have a better survival rate in cities.

刺猬也被发现容易生活在城市地区，因为他们的天敌不愿意离开乡村的环境，所以刺猬在城市有更好的存活率。

We had lots of sightings, so all in all we had no difficulties with our efforts to count their numbers precisely.

我们有过很多次观察，所以我们在精确的计数上没有问题。

Our final species is the finest of bird singers, the song thrush.

我们最后一个物种是最好的鸟类歌手，画眉鸟。

On the decline in the countryside, they are experiencing a resurgence in urban gardens because these days gardeners are buying lots of different plants which means there's an extensive range of seeds around, which is what they feed on.

在农村地区数量下降，它们在城市花园中开始复兴，因为现在园丁们买很多不同的植物，这意味着有周围有大量的各类种子，这正是它们所吃的。

Another factor is the provision of nesting places - which is actually better in gardens than the countryside.

另一个因素是提供筑巢的地方，实际上在花园中比农村好。

Hard to believe it, but it's true.

很难相信，但这是真的。

Incidentally, we discovered that a massive new survey on song thrushes is about to be launched, so you should keep an eye open for that.

顺便说一句，我们有大量关于画眉的新发现现将会推出，所以你要密切关注。
