At just about every meeting we have a short presentation
on current birding topics such as problem IDs, birding techniques such
as field sound recording and photography. Hopefully these presentations
will last about ten interesting minutes. Details of these presentations
will be put up on the DVOC webpage as a permanent online resource for
everyone. Members are encouraged to participate in these sessions with
their own additional comments and wisdom on the topics.
