Common grackles use physical displays and vocalizations to communicate. Common grackles produce one song type, which is individually distinctive and is probably used as identification. The harsh song is said to sound much like a squeaking, rusty gate. The male song is most often heard around the date of the first copulation, and its frequency decreases over the course of incubation. Females sing much less frequently than males, and appear to sing most often when song-answering with their mate.

The House Finch (Carpodacus mexicanus) is a member of the finch family (Fringillidae), which are small, seed-eating songbirds. These sparrow-like birds are common visitors to backyard bird feeders. Adult House Finches are 5–6 inches (13–14 cm) long with a wingspan of 8–10 inches (20–25 cm) and weigh approximately 1 ounce (25 g). Both males and females have brown back and wing feathers with dark streaks and white tips, and their belly or underside is white and heavily streaked with brown. House Finches have black eyes, dark brown legs, and a short, brown beak with an arched top edge. The male is characterized by bright red/orange or yellow color around his eye and on his neck, upper chest, and rump. During the late summer, the male molts completely, replacing all of his body feathers. During this period, the male eats brightly colored foods (such as red berries and flower buds) that will determine how brightly colored his new feathers will be. In contrast, the female has a solid brown head and lacks red markings. Juvenile House Finches are similar in appearance to the females but lack white bars on their wings. The song of the House Finch is a high-pitched, warbling "chee–er!"

The Eastern Chipmunk (Tamias (Tamias) striatus) is a small squirrel-like rodent found in eastern North America, the sole living member of the chipmunk genus and subgenus Tamias. Their name comes from the Odawa word ajidamoonh or the Ojibwe word ajidamoo, which translates literally as "one who descends trees headlong".
They have reddish-brown fur on their upper parts with 5 dark brown stripes and contrasting light brown stripes along their backs and light underparts. They have a tawny stripe that goes from their whiskers to below their ears and light stripes over their eyes. They have a dark tail. They have 2 fewer teeth than other chipmunks and have 4 toes each in the front legs but five in the back legs.
They live in deciduous woods and urban parks in southern Canada and the eastern United States. They prefer locations with rocky areas and shrubs to provide cover. These animals are mainly active during the day, spending most of their day foraging for food. They eat bulbs, seeds, fruits, nuts, green plants, mushrooms, insects, worms, and bird eggs. Like other chipmunks, they transport food in pouches in their cheeks.

The Carolina Wren is one of our great singers, a beautiful singer and a most persistent singer. It is one of the few birds that sing more or less during every month in the year, though it sings most persistently and most enthusiastically during the late winter and spring months; it sings in all kinds of weather, spring sunshine, summer rains, or winter snowstorms; during the height of its song period it may be heard all through the day, from dawn to dusk. It has a varied repertoire; the songs of other birds are often suggested, or perhaps imitated, leading to some confusion at times. But it has a very distinct and characteristic song of its own, which is unmistakable.

The eastern goldfinch belongs to a group of small, short tailed finches which includes the other American goldfinches and the siskins. These birds are closely related to the redpolls (Acanthis) and have traits in common; they collect in flocks during most of the year and constantly give their characteristic notes as they fly restlessly from place to place. They give the impression of being high-spirited birds, always happy and full of gaiety.
