First use IMAGE > MODE to change from Index to RGB....otherwise you can't do anything.
Unlock the background layer if it isn't already.
Use Ctrl + J to duplicate the layer.
Then use the 'Lasso' tool to make a rough, but close, marquee around the crow.
Right Click INSIDE the marquee and select 'Layer Via Copy'. Turn OFF this new layer's visibility.
Select the duplicate layer.
HOLD Ctrl and CLICK the thumbnail of the invisible layer.
RIGHT Click inside the marquee again and select 'Fill...'
Choose 'Contentent Aware' from the dropdown and also check 'Color Adaptation'....then OK.
Turn on the visibility for the 'crow', select the 'Move' tool and drag it to the left as far as you need.
Change the layers 'Blending Mode' to something you are happy with.....for me, 'Darker Color' worked ok.
If you need to you can always add a mask to remove anything you don't want to see.
Regards.
