This study tests if 110-120 MHz RF fields affect magnetic orientation in Eurasian blackcaps, finding reduced but not eliminated orientation capability in the altered magnetic field condition.

The paper analyzes Emlen funnel data to determine orientation ranges and provides guidance for improving experimental design and sample size calculations in magnetic orientation studies.

The paper identifies four horizontal cell types in two bird species and describes their synaptic connections to photoreceptors, suggesting functional roles in intensity and color processing.

The paper compares retinol binding protein and cone-specific G-protein as potential effectors in cryptochrome signalling, finding no robust interaction between retinol binding protein and cryptochrome 4a without retinol.
