A number of events are being recorded at the UWM Field Station, chiefly concerning the earliest arrival dates of certain birds and the earliest flowering dates of native woodland and bog plants. In the table below are listed some events which may be observed during the months of April and May. Those starred (*) are of particular interest to researchers at the Field Station, and any observations by our readers will be appreciated.
