Recently observed large numbers of brown swallows feeding over a freshwater marsh in Guangxi, China. Uncertain whether they are Bank Swallows or Pale Sand Martins, and according to the ID guides the two are distinguished based on clarity/definition of breast band and overall darker color brown in Bank Swallow. This has been difficult for me to judge, so submitting some (distant) photos here for help, for those who are more familiar with these species.
