Birds (and bees) dive into flowers to drink up the "nectar", sweet juices produced within the flowers. Right next to the nectar are the stamens and pistils, which are the male and female reproductive organs; the birds and bees get pollen from one flower on their bodies, and spread it to other flowers.
We call this "symbiotic" behavior; two completely different organisms that evolve together so that each benefits the other.
And it isn't a matter of "the plants _want_ to attract birds"; there is no consciousness involved. The birds do their bird things, and it "just happens" to benefit the plants; the plants create the nectar naturally, without knowing that it feeds the birds and bees.
all sorts of plants attract the hummingbird!
Plants recognize the appearance of birds through visual cues such as color, shape, and movement. This recognition helps plants attract birds for pollination or seed dispersal.
Sparrows , song birds , Dove , Mockingbirds , Hummingbirds ,
Grasshoppers eat all leafy parts of plants growing in the yard and attract birds as their prey.
Plants produce sugar in the sap, nectar and fruits that attract insects, birds, etc. needed to pollinate and protect the plants. We are the ones who consider the pollinators pests.
More important that size is the depth; if you want to attract songbirds do not exceed a depth of 2 inches or they won't settle on it.
Birds can see the colour red very well and are often attracted to it, so if a plant has red berries these are often eaten by birds. Also, in the tropics, red flowers are often visited by birds for their nectar (like hummingbirds) and their pollen is also distributed by birds. Also, many plants attract insects that are in turn eaten by birds. ^^
Plants produce flowers as a reproductive structure to attract pollinators like bees, butterflies, and birds. The purpose of the flower is to facilitate the formation of seeds through the process of pollination, allowing the plant to reproduce and grow offspring. Flowers also contain the plant's reproductive organs, such as pollen and ovules.
The colors and odors are sensed by insects and birds which are attracted to the plant. The birds, etc. carry pollen from plant to plant, and facilitate the reproduction of the plants.
The flower petals are bright in color so as to attract pollinators such as insects, birds, and animals to facilitate reproduction in plants.
Flowers attract pollinators such as bees, butterflies, birds, and other insects. These pollinators help transfer pollen from one flower to another, allowing for the fertilization of plants and the production of seeds.
To attract pollinators, such as insects, which make reproduction possible and continue their species.
