What are your plans for the weekend? Well you could have a go at bird watching, and don't worry if you haven't got any experience.
That's because the RSPB is holding another Big Garden Birdwatch weekend - and they've been doing it for nearly 30 years.
The RSPB wants you to spend an hour in your garden, or on your balcony "spying on the neighbours" - the winged variety that is.
This morning on Breakfast:
Sarah Campbell found out what the Big Garden Birdwatch will involve.
A recording of our interview will be available shortly.
All the information you need including how to download a sample form to log your efforts, then send to the RSPB via the link below You can also get a form by calling 0870 600 7108  Clue: might be obvious, or not? |
If you want to brush up on your observation skills, we've set you a little challenge to get you in training for the big event, this weekend. There are four images on this page, one at the top and three on the rest of the page.
Look at all four images on this page and see if you can identify the species of bird.
Some of them are quite hard and not so obvious, but look for the clue in the caption beneath each picture.
 Clues: a type of finch |
If you to know the answer, hover with your mouse over the image - and the correct name of that species will pop up
Common visitors
The RSPB's Big Birdwatch annual survey aims to find out which birds are the most common visitors to UK gardens in winter.
It also keeps an eye on how others are faring and produces a snapshot of winter bird populations.
The RSPB says you don't need to be an expert and the survey only takes about an hour to complete.
 Clue: the colour is in the name of this species |
The house sparrow claimed the top position for the most birds seen in gardens in 2006 but the species has shown a rapid decrease since 1979, dropping from 10 birds per garden to 4.4 .
The starling, beaten to the top spot in 2006 by the house sparrow, has seen its numbers plummet from 15 per garden to an average of 3.64, a decline of 76 per cent.
However, it's not all bad news. The greenfinch and great tit have both seen their numbers increase over the past 28 years
