Style for "Waterbirds"

Hi,  I’m seeking an output style for the journal “Waterbirds”.  I searched the database and contacted the editors with no luck.  Can anyone suggest a similar style?

Instructions for Contributors attached as PDF. 

Any help greatly appreciated.

I suspect you weren’t able to add the PDF or link due to forum restrictions for new members.

I looked at those, and identified one that I think might work (attached in a zip file), without too much manipulation from this collection made long ago by a clever member of these forums (here is the whole thread with many defined styles).
