"Cutting Edges: Contemporary Collage" exceeded all my expectations (thank you interlibrary loan). Here is a selection of birds and one tiger from this survey that was published earlier this year.
Emmanuel Polanco, La and Do, 2010
Dolan Geiman, Zerelda's Weathervane, 2008
Dolan Geiman, Field Guide Riverbank, 2008
Emmanuel Polanco, The Raven, 2009
Emmanuel Polanco, Le Tigre, 2009
Since I only now realized three of the above images were from Emmanuel Polanco, I went to his website and discovered even more bird collages! All the images below are from the link above.
Also check out Dolan Geiman's website (this image provides the bird and cat link).
