Alex Warnick is an artist who specializes in watercolor paintings of birds. Her website portfolio is divided into sections for Painting and Illustration, though her technique seems basically consistent.
She combines a naturalistic approach to the birds themselves, setting them off with bits of flora that act as design elements.
In addition to her portfolio, you an find additional examples of her work in her website’s “Store” section, as well as on her blog.
There is a relatively extensive interview with Warnick in an episode of Andrew Tischler’s The Creative Endeavour Podcast (YouTube).
