Detailed explanation-1: -Callistemon(bottle brush) is pollinated by birds and is an example of ornithophily . Salvia is insect pollinated and is an example of entomophily .

Detailed explanation-2: -Apis bees are effective pollinators of Callistemon sp. and reported to increase fruiting rate (64–92%), seed numbers (38–59%) and normal seeds (82–84%) in Cameroon (Tope et al., 2012). Differences in sources of pollination can affect seed number, fruit shape and size in different plant species (Palma et al., 2008).

Detailed explanation-3: -Plants bearing typical bird flowers are cardinal flower, fuchsia, red columbine, trumpet vine, hibiscus, strelitzia, and eucalyptus, and many members of the pea, orchid, cactus, and pineapple families.

Detailed explanation-4: -Pollination by birds is called Ornithophily. Since most flowering plants cannot pollinate on their own, they have to rely on other animals. Many small birds, such as sunbirds and hummingbirds are key pollinators.
