My pics above are definitely straight from camera with no PP other than re-sizing to display on the web.
The saturated colors: "L" lens on a full frame body shot at ISO 100, properly exposed in Av mode with saturation set to +2. I shoot saturation at +3 unless there are people in the shot when I dial it back to +2 because +3 can produce orange skin tones. These settings only effect the JPGs. RAW's aren't processed in camera (by definition).
I think I've posted this here before but this is straight out of camera with +3 saturation.
As for the photo of the three ladies, high speed sync with a flash is the best way to fix that and have a balanced foreground and background:
For the bird, MadCow has given you excellent advise. Getting a dark bird exposed properly when flying is very difficult to impossible with a short lens. In fact, birds in flight may be one of the hardest types of photography to master. MadCow is right about getting the composition right before you take the shot but, another advantage to shooting max res is that it gives you more room to crop the image after its taken and still have suitable resolution for printing.
One thing I like to do is enable AEB and take three shot strings either one stop or 2/3 stop apart. Photography isn't magic. It's just a matter of having a lot of practice so that you know the right tricks and when to use them.
Also, be very careful with "cheap" memory cards. One day, one WILL fail on you and you'll lose a bunch of photos. In fact, it's always better to have multiple smaller cards rather than one big card for this same reason.
