Short answer: Yes, the seed hulls are similar as they are both "asters".
Nyjer and sunflower seeds are popular bird attractors at the winter feeding station. Both seeds have an edible oil, though it is the sunflower that became a production crop in the U.S. Actually "Niger" or "nyjer" (Guizotia abyssinica) is a close relative of the sunflower, as they are both from the Asteraceae (Aster) family (nyjer not a thistle -that was a marketing ploy by birdseed producers, believe it or not!). The Aster family has a specialized fruit covering called a "cypsela". If you look at the nyjer seed very closely with a magnifying glass, you can see how similar it is to the sunflower, especially the black oil sunflower seed.
Nyjer seed does not have a shell like sunflowers. Wild birds eat all of the nyjer seed.
Yes, Nyjer seed is also known as thistle seed.
The shell of a sunflower which is white and black striped protects the seed inside of it. The seed, if planted becomes a sunflower plant.
To effectively shell sunflower seeds, first crack the shell with your teeth or a nutcracker. Then, use your fingers to remove the seed from the shell. Repeat the process for each seed.
Nyjer seed.
A sunflower seed is the fruit of the sunflower. The seed is referred to as a achene when it is inside of its shell or pericarp.
peanut shell??? Sunflower seed
Birds such as finches, sparrows, and siskins are attracted to nyjer seed feeders.
It won't because the seed will be dead
No, nyjer seed is not toxic to people. It is a type of seed commonly used in bird feed and poses no health risks to humans when consumed.
Birds that commonly eat nyjer seed include finches, such as goldfinches and siskins, as well as sparrows and doves.
For the sunflower (Helianthus annuus), the seed is a multilayered future plant that is enjoyed as a food source by many. What you see, when you have a sunflower seed, is the hard shell. It can be all black or striped. Break that open and you have the actual seed. The outer most covering on the seed, usually you don't notice it, is call the integumentary or seed coat.
