Very nice composition and so beautifully detailed Yves. The weeping grasses you refer to are millet which provide a favorite seed for these birds and going by facial markings this cute little guy looks a lot like a Song or Savannah Sparrow, both of which are common to your area I think. This is a very nice photo and I'm glad you shared it with us.
I like this shot as well Yves, not so strange. The little sparrow is camouflaged but with your chosen DOF and positioning he stands out perfectly. The green leaves winding up the composition add a nice splash of contrast. Well done Yves, I would say another artistic capture.
I like this one. The controlled DOF and focus all compliment this great composition.
