Wood Pigeons were London's most popular visitor to schools
London's children and teachers can become birdwatchers from the comfort of their classrooms and take part in the world's biggest bird survey, the RSPB Big Schools' Birdwatch.
The annual survey runs from 18 January to 1 February and encourages children and their teachers to identify and count the birds that share their school environment.
Last year's survey revealed that the most common bird in Greater London's schools was the wood pigeon with an average of 4.62 seen per school.
Feral pigeons and blackbirds completed the top three, with an average of 4.42 and 3.75 respectively.
More than 5,000 schoolchildren from Greater London took part in last year's birdwatch. Nationally there were nearly 90,000 children and teachers taking part from more than 2,000 schools.
RSPB London spokesman Tim Webb said: "The activity is suitable for children of all ages and appeals to teachers because it's fun, easy and simple to set up."

The RSPB has found that feeding birds is an easy way to start teaching children about wildlife. Providing food and water brings birds close enough for children to observe their behaviour and colours.
All schools' need to do to take part is watch and count the birds in their school grounds or a nearby public space for one hour.
Like other schools you can make the activity the centrepiece of a whole week devoted to learning about wild birds.
Remember to send one set of results to the RSPB.
Combined with the data gathered from the Big Garden Birdwatch, scheduled for 30 and 31 January, it gives the conservation charity a snapshot of bird numbers and species across the UK.
Tim added: "We want to hear about what's out there, all sightings are useful to us! Our online results form is an interactive computer programme that the whole class can use.
Blackbirds were the third most common sighting
It allows teachers and pupils to build graphs and charts using their own results and then compare them with others. It really brings to light the difference between rural and urban schools."
You don't need to be an expert twitcher as the RSPB has produced a free schools pack containing everything required. The emphasis is on having fun and joining in. The pack includes guidance notes, a full colour bird identification poster, counting chart and survey form.
