The little grey bird is a tufted titmouse and the bird with the bright orange beak is a female cardinal, or Mrs. C. as Richard calls her!
At this time of the year, the male cardinal (the very bright red one) will FEED the female...I saw this just yesterday and ran to get the camera, but alas, the male had flown away and it was another missed photo opportunity. In North America, the cardinal is very common. When my in-laws visited from England, they were very excited at their first sight of a cardinal. It is such a beautiful bird, right in my backyard of Planet Earth!
UPDATE: I didn't take this photo but I found one for you!...Beak to beak! Happy Spring to all!
