Birds in Dual-Pol, KMLB

We had a nice ascending bird flock over the St. Johns basin at sunrise. Look at the upper right frame where Dual Pol differential reflectivity (Zdr) shows strongly positive values (red/pink) indicating horizontally aligned reflectors. Birds with extended wings in flight. Correlation coefficient (CC) values showed larger variation supporting non-uniformity in the sampling, also reasonable with non-meteorological biological echoes.
