Scrub Jay with materials

Been watching a Jay couple build a nest, this fellow is waiting as his mate finishes weaving in her bundle.
ATX85, Digidapter/ GH4/ 20mm lens
f1.7, ISO 1600, 1/2500 sec.

Here is the same bird after it leaped into the bush,
I changed the setting to ISO 800 1/100 sec.
Amazing difference in detail
