Does a resource exist (either hard copy or internet) that includes every age, gender, plumage and other variant-specific detail for Western North American Birds?
Here's an example of what I mean, using a Mallard:
Mallard
-Drake (adult)
-basic plumage (description and photos, in flight and perched)
-breeding plumage (description and photos, in flight and perched)
-alternate plumages (description and photos, in flight and perched)
-Hen (adult)
-basic plumage (description and photos, in flight and perched)
-breeding plumage (description and photos, in flight and perched)
-alternate plumages (description and photos, in flight and perched)
-Drake (juvenile)
-basic plumage (description and photos, in flight and perched)
-breeding plumage (description and photos, in flight and perched)
-alternate plumages (description and photos, in flight and perched)
-Hen (juvenile)
-basic plumage (description and photos, in flight and perched)
-breeding plumage (description and photos, in flight and perched)
-alternate plumages (description and photos, in flight and perched)
etc.
In this example, the section for Mallard would contain, at minimum, 9 different descriptions, with at least 18 drawings/photos.
Or, for Gulls:
California Gull
-Adult Male (female, juveniles, etc.)
-1st winter plumage (description and photos, in flight and perched)
-2nd winter plumage (description and photos, in flight and perched)
-alternate plumages (description and photos, in flight and perched)
In other words, every possible variation for every species. Is this too much to ask?
I'm still a novice, but I find that it's simply impossible to ID many birds (esp. females, juvies, basic plumage) using only my field guide and image searching.
Most field guides list some of the above, but not all. I realize the difficulty in creating a resource with all this info, particularly drawings or photos, but I was still wondering if something existed somewhere.
Or, perhaps, there are family-specific resources that contain this type of detail?
I know I might be asking for the world here, but I thought I'd see what you experts recommend. Thanks in advance for any guidance here.
