winter - at least until the birds eat them all! These evergreen hollies are a wonderful addition to the garden and provide great nesting sites for many species of birds including mourning doves and robins. Berry laden holly boughs can also be cut in December for use in holiday arrangements - an added bonus!  

  
Many ornamental species of Sumac (Rhus) and Viburnum produce berries that ripen in late summer or early fall and remain on the shrubs into the winter. These shrubs attract a variety of different birds to the garden including flickers, woodpeckers, cardinals, robins, bluebirds, sparrows, and grosbeaks.  

Pyracantha berries

There are several beautiful cultivars of Scarlet Firethorn (Pyracantha coccinea) that have spectacular berries in shades of red, orange, and yellow. These shrubs can be used as a specimen in the garden, as an informal hedge, or espaliered on a wall or trellis. In addition to feeding on the berries, many birds also like to nest in these shrubs because the branches are covered with sharp thorns which provide protection from predators.

Moose eating mountainash

Mountainash (Sorbus spp.) produces spectacular clusters of brilliant red or orange fruit that is a favorite of many different birds and even larger critters. I was sent some photos of a large bull moose noshing on the berries of Mountainash outside an office building in Anchorage, Alaska!
"He doesn't come everyday, but when the snow gets thick and it is harder to forage in the woods, he comes into town for a snack." 
How crazy is that to see outside your office window - and in the middle of the city. Never a dull moment!

Rose hips

Rugosa Rose (Rosa rugosa) and many varieties of honeysuckle (Lonicera spp.) also produce loads of rose hips and berries to feed the birds and other wildlife during the winter.
