| This response to rising temperatures has been documented in birds, insects, plants and mammals across a range of continents, and it is no surprise that the UK's birds should be changing their habits too. | This response to rising temperatures has been documented in birds, insects, plants and mammals across a range of continents, and it is no surprise that the UK's birds should be changing their habits too. |
| In some species, the shift has been shown to be damaging, as it means key foods are no longer available when the youngsters need them. | In some species, the shift has been shown to be damaging, as it means key foods are no longer available when the youngsters need them. |

| "The rate of redistribution of some water birds has been dramatic in recent years, but for some species we still know little about the extent to which decreases in numbers in the UK are due to redistribution to other parts of their range or real decreases in overall numbers," said Richard Hearn, water bird monitoring programme manager at the Wildfowl & Wetlands Trust.The wet 2007 summer was a boon to song thrushes | "The rate of redistribution of some water birds has been dramatic in recent years, but for some species we still know little about the extent to which decreases in numbers in the UK are due to redistribution to other parts of their range or real decreases in overall numbers," said Richard Hearn, water bird monitoring programme manager at the Wildfowl & Wetlands Trust.The wet 2007 summer was a boon to song thrushes |
