Hi Alan,
You can do both.
Listing of all sightings for ducks, etc
This is what the Taxonomy filter is for on the reporting screen and othe screens. Use that to filter on Animalia - Chordata - Aves - Anseriformes. See screen shot below. Now you will only get sightings of those things, on the selected taxonomic list, that occur under that branch of the taxonomic tree.
Earliest dates for species
Use the Ignore year checkbox (Reports and View/Edit sightings) and then sort ASC on Date. You will get a list of all sightings sorted by dat of the year (ignoring the year).
Also, new in V3.7 is a new graphing feature that shows this to you graphically!!
