Bird Feeding: Fact
vs. Fiction
BIRD
FEED FACTS
We currently sell
suet,
bird
seeds, and squirrel
feeds. However, before jumping to those store categories may we suggest
a review of bird seed facts vs. fiction. A landmark study conducted by
the U.S. Fish & Wildlife Service shed new light on bird feeding practices
throughout the United States. The study rated the multitude of bird feeds
available and ranked them in accordance with desirability to birds. Please
note that this study did not include an evaluation of suet
products, important to many species as a source of fat in their diets.
A Bird’s World strives to bring you information based on independent
scientific studies such as these. A synopsis of the findings of this study
is as follows:
- Feed preferences
were relatively consistent throughout various geographic locations in
the United States. By and large what a bird likes to eat in Baltimore,
his counterparts will eat in Seattle.
- Sunflower seeds
and White Proso Millet (WPM) were the most generally preferred feeds
for virtually all species.
- Oil-type
sunflower seeds were the most preferred of any sunflower variety
overall, though there were specie specific preferences within the sunflower
category.
- The type of
feeder utilized has an impact on the frequency of feeding activity (please
see our feeder section).
- Commonly sold
seeds such as milo, cracked corn, and wheat are less appealing to wild
birds; this was true for buckwheat, flax, most millets, canary seed,
oats, rice, safflower, sorghum, thistle and wheat.
- Offering either
black
oil sunflower or White Proso Millet separately is more effective
than most general commercial mixtures. While the cost of using commercial
mixes is initially lower (eaten less frequently, and addition of bulk
amounts of less expensive seed within the mixture) it is less effective
and therefore not quite the bargain most people perceive. We carry a
full
line of Sun Country Farms bird seed products which adhere to the
high quality standards established by this study.
Bottom Line:
Avoid all but proven mixed products, normally sold commercially as premium
and value product lines. Purchase oil-type
sunflower seeds and white proso millet and present them separately
in different feeder styles (see
our feeder section). The birds feeding on WPM prefer ground or large
platform feeders, while oil-type sunflower feeders prefer an elevated
feeder with small perching areas, such as that found in tubular
feeders. The good news is that following these recommendations saves
you money, provides the birds what they really need to flourish, and attracts
the greatest variety of species to your backyard.
SEED
VARIETY SUMMARY:
- Buckwheat: Mourning
doves exhibited limited interest, finding it only one-fourth as attractive
as WPM.
- Canary Seed: More
expensive and less attractive than White Proso Millet for those species
that would consume it.
- Cracked corn: “Fine
cracked corn” is much better than the course variety, however not as
effective as WPM and BSS (Black Stiped Sunflower Seeds). Also, this
feed has a tendency to mold and merge in feeders.
- Flax: Substantially
less attractive than the WPM and BSS.
- German (Golden)
Millet: Although an attractive food to small sparrow-like birds and
mourning doves, less attractive than WPM.
- Red Proso Millet: Different
variety of WPM, though less attractive overall.
- White Proso
Millet: Rated most attractive for those species illustrating a preference:
mourning doves, house sparrows, brown-headed cowbirds, white-crowned
sparrows, white-throated sparrows and song sparrows. Only hulled
sunflower kernels and pieces were preferred over WPM by white-crowned
and white-throated sparrows.
- Oats: Whole
or hulled, there is limited interest in this feed. Prone to insect infestation
and the chosen food of starlings.
- Peanuts: Peanut
hearts illustrate little value as food, with the exception of starlings.
However, peanut
kernels are preferred by blue jays, scrub jays and tufted titmice to
even BSS. Keep in mind these species will also consume BSS (saving
you money over the cost of Peanut kernels).
- Rape Seed: Though
occasionally found in "premium" mixtures, and a primary ingredient to
domestic canary food, wild birds could care less. Save your money.
- Rice: Unattractive
to all species of wild birds.
- Safflower: If
you are looking to attract cardinals while discouraging most other species
this is what you should use. Otherwise, stick to BSS and WPM.
- Milo or Sorghum:
Milo is an unattractive food to all species, despite the fact that it
is found in many commercial mixes. Sorghum is now produced as a “bird
resistant” strain to stop crop destruction, they’ve done a good job-
the birds don’t like it.
- Black striped
sunflower seeds: BSS is very effective as a bird feed. The crop
is screened so that larger seeds are sold for human consumption, birds
prefer the smaller variety.
- Eller: a small
form of BSS. Cardinals, purple finches, house finches, house sparrows
and white-throated sparrows all showed a preference for Eller over the
regular BSS, while blue jays, scrub jays and tufted titmice preferred
the larger BSS.
- Large Black
Striped Sunflower Seeds: Jays and tufted titmice were the only species
that preferred this large seed (obtained by screening).
- Gray Striped
Sunflower Seeds: Although this large sunflower seed is visually appealing
to people, very few birds preferred it. More expensive, it is inferior
substitute for BSS.
- Hulled
Sunflower Pieces and Sunflower Kernels: Whole or broken kernels
of hulled sunflowers were very attractive to American goldfinches and
house finches. Less mess, since they are hull-less.
- Oil-type
Sunflower Seeds: We have a winner!
This is the number one preferred food by most species that will visit
your feeder. Smaller than BSS even small seed eating birds enjoy
it. American Goldfinches preferred it to thistle. It’s less expensive
than BSS; lasts longer in feeders since it there are 2-4 times as many
seeds in a bag. Less expensive, overall favorite.
- Nyjer
(Thistle): With the exception of goldfinches, mourning doves and
house finches, this seed is generally unattractive to all other species.
Tubular
feeders are best if your intent is to attract finches. Based on
the information available in studies, you could also buy the small oil
type sunflower seeds and save money, many of the tubular
feeders allow you to offer both types of seed. We offer a proprietary
blend known as Finch
Feast which will save you money and attracts the greatest variety
of birds based on this information.
- Wheat: Commonly
included in commercial mixes, its value is suspect, unless your intent
is to attract only mourning doves and discourage all other species.
The doves prefer WPM by the way.
