A few Egret and a request for help

I really enjoy shooting birds one of my favorite are egrets. The problem I have is that they are often against a dark background and I have to balance between setting the exposure down and center weight metering or a combination of both
Is there somthing else I can try that does not either blow out all the white or get the background to dark
Or is the combination of a bright sun, bright white bird and a dark or muddy background a difficult combo
Help and critique wanted
Anyway here are a few of the white devils
