Looks like winter to me!
Nice perch, good flash work, sharp.
Wish his head was turned back towards us just a bit.
I might consider darkening the midtones just a bit, as they look a little washed out.
In general, I like the background, but I might try to blur the curving line that intersects with the back of the neck.
Perhaps a sliver more room to the left if you have it, so the tail doesn't seem crowded into the corner.
I calibrated my monitor with a Spyder 3 Pro and it seems that it is now a little bit too dark (and I produce photos that are a little bit too luminous).
Please take my exposure comment with a grain of salt. I am at my work monitor, which tends to render images a bit lighter than they should be. I will try to remember to recheck it tonight at home.
Very nice feel to this one. Loved the sharpness. With birds oriented diagonally, cropping is always a bit tricky. I think a wider crop might work better here. I find it a little tight at top and left.
Allo Josée. I agree with the suggestions offered. The repost is an improvement, but I still think it looks a little bright overall...I know it can be difficult to calibrate to the point you were used to!
