Tits in urban habitats

With colleagues from Anglia Ruskin University, Julia Mackenzie has been collecting long-term data on the breeding success of Blue Tits and Great Tits in urban habitats (CUBG and more recently Cherry Hinton Hall). Ringing and other biometric data have shown breeding success in both species to be poor in urban environments. This is mainly due to the physically patchy and botanically variable habitat, which make finding suitable food for chicks extremely difficult.
