Tree Swallow

Tree swallow numbers have been increasing at RNWR. They had been gathering mostly over Big South Lake, but this last Friday many had moved to the wooded areas along the Auto Tour between markers 9 & 10.
These two males appear to be challenging for breeding territory, perhaps for the possible nesting hole just below.
