Red-necked Grebe



The graph is based on data from Seasonal Field Reports and may be incomplete.  Note the actual number of birds recorded on the left of the graph to get some perspective and understand that common species are often under-reported and some reporting biases are evident. It is also quite common to have a rare bird reported by several people which inflates the numbers.
