Mid level 5 m • 3. Top Level 10m Each set was opened for 3‐4 days Nets checked 1hr and 30 min intervals Opened nets: 6 am Closed nets: after 5 pm Study carried out on the 6th –14th August Data Collection Species Net height Date and Time Sex and Age Moult, Brood Patch and Biometric measures Nail Polish marking for recapture control Data AAlinalysis MS Excel 2007 Statistica 9 Repeated Measures ANOVA Canoco 4.5 RDA ‐ Redundancy Analysis Questions 1. Are canopy mist nets more or less effective than ground nets? 2. Is the abundance of birds different between high (10m), Mid (5m) and ground level? 3. Is there a difference in the species composition between high (10m), Mid (5m) and ground mist nets?

There is a difference in the number of individuals between sites. Food resources can be higher at various sites Birds can follow certain flight‐routes No species preferences confirmed Data set too insufficient Distance between net heights were not far apart enough to show preference Thank you for your attention.
