George Rabin, a regular contributor to Avon Birds, and Ed Thurlow won the “GSK UK Young Scientist of the Year Award 2017” at the BigBang Young Scientists and Engineers Fair in March with a project investigating garden birds’ responses to coloured supplementary feeders.
BBC Springwatch featured the project and
encouraged schools to participate. The larger the data set that can be
gained, the stronger the conclusions. Although the project has been fortunate to gain coverage in local and national media, it would be of great
interest to all of those involved (birds included) to see results from a
national project. The project has been fortunate enough to gain coverage in national and local media. As a result of the BigBang win the team is representing the UK to compete at the EU Contest for Young Scientists in September and hope
the project will be further publicised so others can take part.
Equipment
Five
identical seed port bird feeders made of clear plastic.
Four
paint colours: Red, Yellow, Dark Blue and Green, acrylic or preferably oil paint.
Bird
food: sunflower seed hearts, peanuts, suet pellets and meal worms are good bird foods.
Bird
feeder pole/tree (to hang the feeders).
Scales.
Methodology
1) Gather
your 5 bird feeders and 4 paints. Set one of these feeders aside, as this
will be your control
2) Take
the other 4 bird feeders and paint each one a different colour. Avoid
painting the feeding ports as this could harm the birds (most feeders can
be dismantled to do this). Add a strip of tape down the side that can be removed to make a gauge to see the food level or just open the lid to see how the level is dropping.
3) When
dry, fill up each bird feeder.
4) Place
outside and try to space out feeders evenly and at a similar height as
this will stop the birds preferring one due to its position rather than
colour.
5) How
much recording you do is up to you. If possible, count the number of visits to
each feeder by any species for 15/20 minutes each day. Try to make a note of which species use which colour. In terms of counting the
visits, the more the better! Add up all the visits to get a rank for each
feeder.
6) Once one feeder reaches below 1/3 full, weigh all the feeders (to get a
rank) and refill all the feeders. Calculate the overall amount of food
eaten from each feeder to get an overall rank.
7)
Continue the experiment for as long as you wish
8) The survey https://www.surveymonkey.co.uk/r/98JW8MZ asks questions about the popularity of the feeders (ranked 1-5), which species preferred each feeder, and other details about how you did the experiment.
