Determination of Needs for Backyards

Site Assessment

Mark Johns

NC Wildlife Resources Commission

 

·        Prepare an inventory of your property and identify all habitat elements already in place.  List all sources (FOOD) that you can identify (or get some qualified help) which might provide wildlife foods.  List potential wind and weather breaks, as well as places (COVER) for wildlife to rest and/or hide.  What NESTING opportunities (trees/shrubs) exist?  WATER sources present?

·        Set a budget and stick to it.  You can plan for one season, or better yet 3-5 years.  Your major expense (besides tools you may need) if you do the work yourself will be plants and landscaping supplies.

·         Make a plan.  List what you have, and list what you will need to improve your property for birds.  Put your property design on paper (make a drawing) and put in all of the inventoried food, water, cover and potential nesting sites for birds.  This will help you understand what is missing in your backyard.  All birds need particular aspects of food, water, cover and places to raise young in your backyard.  Consider what bird species you wish to attract to your backyard habitat.

 

Typical Species

 

1-Ruby-throated Hummingbird:  This is the breeding hummingbird of North Carolina.  A variety of hummingbird feeders can be bought and stocked with plain sugar water (a quarter cup of sugar for each cup of water), and many plants can provide natural nectar sources for hummers in your yard.  Try and plant nectar sources that will provide food (bloom) throughout the breeding season and migration periods.  Fresh fruit pieces will attract orioles, catbirds, tanagers, some warblers and mockingbirds. Some warblers and orioles will visit nectar feeders.

                        Cardinal Flower                                    Columbine

                        Jewelweed                                           Penstemon spp.

                        Coral Honeysuckle                             Trumpet Creeper

                        Wild Azalea                                      Buckeye

                        Hawthorn                                             Crossvine

 

2-Bluebirds:  Bluebirds need open spaces to hunt for small critters on or near the ground.  They will also eat fruits, so you can plant certain woody plants to provide natural bluebird food.  Nesting opportunities can be provided by putting up bluebird boxes with predator guards on poles along wood edges or in open spaces in your backyard.

                        Hollies                                                  Chokeberry

                        Viburnums                                            Elderberry

                        Blueberries                                           Spicebush

 

3-Purple Martins:  These birds feed on flying insects, especially large ones, and need martin houses or gourds for nesting.  Make sure to take down these nesting structures down or close the holes after martins leave in late summer to head back to the tropics so that nuisance birds like house sparrows and starlings can’t use the structures.

 

4-Chimney Swifts:  These birds feed on small flying insects and spiderlings and nest in brick chimneys.  They are present during late spring, summer and fall in our area.  To keep out unwanted chimney swifts you would have to cap your chimney before they arrive in early April.  Migrating swifts in fall will roost in larger chimneys in impressive numbers.  Chimney swift towers can be built to provide additional roosting chances.

 

Other Birds

 

Some people prefer to provide additional foods in the form of seeds to attract seedeaters like goldfinches, cardinals, chickadees, nuthatches, doves and juncos.  The best seed for your money is black oil sunflower, in that it attracts a wide variety of birds.  Quality seed mixes will have black oil sunflower, striped sunflower, sunflower chips, safflower (squirrels, grackles and other blackbirds tend not to eat) and white millet.  Many people feed niger (thistle) to attract finches, and cracked corn, peanuts and peanuts in the shell can round out the menu in your feeders.  A variety of feeder types and positions in your backyard work best.  Planting hard mast species can also provide food for woodpeckers, blue jays, nuthatches, and many other birds.  Some good species to plant are oaks, hickories, beech, ashes, hazelnut, American hornbeam and hop-hornbeam

 

Offering suet in your backyard can really draw in the birds.  Suet is a high-energy food that can now even be offered in certain forms in warmer weather.  It will often attract birds that otherwise would not come to feeders.  Display in cages to keep squirrels out of your suet if they are a problem.  In bear country, feeding suet might not be a good option.

 

To attract fruit eating birds (many warbler species, tanagers, orioles, bluebirds, robins, cedar waxwings and many more species) you can certainly feed dried or fresh fruits at feeding stations.  A Better plan is to stock your backyard with native fruit bearing shrubs, vines and trees.  Be careful with many shrubs in that they “sucker” and are best not planted along wooded edges.

Active Management

General Habitat Needs

 

All bird species require four basic elements to survive and prosper in your backyard:  FOOD, COVER, WATER and AREAS TO REPRODUCE AND RAISE YOUNG.

 

FOOD:  The ideal wildlife management plan supplies as much food as possible through vegetation to meet year-round needs of a wide variety of species.  Shrubs, trees, vines and other native plants that produce foods such as acorns, nuts, berries, seeds, buds, and nectar should be spaced throughout your property in a visually appealing manner.  Food sources can be supplemented in winter with feeders, and hummer feeders can add important sugar water energy sources for your hummingbirds.

 

COVER:  Wildlife need places to hide form predators, get out of rough weather, or just rest!  Cover can be provided in a variety of ways.  Plants that provide food can also offer cover.  Dense shrubs or trees, especially evergreen species can provide thermal refuge year-round.  Hollow logs, brush piles, stone walls and patches of early successional thickets or meadow all can provide important cover for birds.  Include plants in your backyard that range in size and density from evergreen shrubs to large trees.

 

WATER:  Birds do need water for drinking or bathing.  Water can be supplied in a birdbath, small pool, recirculating waterfall, shallow dish or dripping hose.  Provide elevated water sources for some protection from cats and other predators.  Water will draw unusual birds into your yard.  A dependable year-round water source is best, and keeping it clean is important.  Bird bath heaters or removal of ice may be needed in cold weather.

 

NESTING (Places to Raise Young):  A specific type of cover is needed to provide birds with chances to reproduce and raise young.  Bird houses and nest shelves can be attached to posts or even parts of your house.  Of course, dense shrubbery and trees provides chances for nesting.  Certain species will nest in brush piles, like Carolina wrens.  Many of the smaller plants (especially ferns) in your backyard can provide nesting materials.

 

Plant Species Options

Wildflowers:  Wildflowers are pleasing to look at in addition to their value for birds.  Select a variety of species that bloom throughout the growing season, and try some species in massive clumps and others in multi-species layers around your backyard area.  Strive for a mix of heights and colors.  Don’t be afraid to experiment with different positions in your yard in terms of sun exposure and moisture regarding suggested species.  Strive to use native wildflowers as much as possible, and check with nurseries for planting details.

Woody Plants:  (Trees, shrub and vines for birds) Woody plants can provide food, cover and places for birds to nest.  Placement can be important based on the SIZE that the species can reach at maturity.  Certain trees have root systems that can creep into substructural parts of building if planted to close, and many shrubs readily sucker sprout so are better placed where they can “spread” as they wish!  Be warned that only the “females” of some species produce fruit, like Red Cedar and Hollies.

Water Sources

 

Provide a constant supply of low and high water sources.  From simple, inexpensive sunken dishes on the ground to elevated bird bathes.  ‘Moving water’ is a real draw for birds and will get migrating species to visit your yard that won’t go to feeders.  Consider creating a small backyard pond with rock ledges and shallow depth to allow easy bird access for drinking and bathing.  You can use pre-fab forms or dig your pond and use liners.  Keep your water dishes and bird bathes clean!

 

Feeders

 

Most important is to keep your feeders clean and full!  Provide a variety of feeder types (ground, tube and platform)to augment your bird feeding activities in winter especially.  Take care in how you mount the feeders (and use predator guards when possible) to discourage squirrels (unless you just like feeding them), and provide sunflower seeds as well as small seeds like millet for the small seed specialists.  Place feeders adjacent to cover (10-12 feet away) in most cases.
