観察結果の詳細

After many years of observing RBC in this lake, I have identified four different groups from different sides of the lake. The average group size was 2 to 4. On a single day, I observed 9 different individuals. At first, I studied their movement throughout the whole year, and during my observations in 2024, I saw them almost every month. So, I am confident that they are most probably breeding in this area. Continuing my observation of RBC, I finally spotted one juvenile/immature bird from the FS side of the lake. Bird has a clear white underpart with brown barring. Upper part also much darker than adults and has a some white shaft also clearly visible in this images .
