Juvenile Starlings have confused many a birder - it's all a learning process.
The thing with birding is - a person may get things wrong but as they learn more the less they get wrong.
If you look at the 'experts' on some of the more 'notorious' birding forums, you'll notice that these experts will argue with each other about bird identifications - and they're supposed to know 'everything'
This is the best identification guide available for Warblers. I find it never fails
Oh come on ILR, even I can tell the difference between a gull and a warbler
