What is in this image? Be very specific. Scientific, Engineering style! No emotions, no opinions, no metaphors. Just the facts, as detailed as possible.

The image is a line drawing, presented vertically with a layout comprising three rectangular panels, arranged sequentially from top to bottom, each containing either one or multiple elements. In the first top panel, there is a depiction of a bird, with an outlined heart shape above it, positioned centrally at the upper right of the bird. The bird is illustrated with a stylized form featuring a rounded body, a simplistic wing structure represented with minimal lines, a triangular beak pointing upwards, two small round eyes, and a tuft of feathers on its head resembling a crown. It is perched on a branch segment that diagonally crosses the panel from the upper left corner to the lower right. This branch includes three leaves distributed along its length, each leaf consisting of an ovate shape with a line through its middle, representing the leaf vein.In the second middle panel, a similar bird is depicted. This bird also showcases a rounded body, wings, and a slightly open triangular beak, oriented sideways as if in a calling or singing posture. The eyes are round, and there is also a feather tuft on the head. Positioned directly on a branch that spans from the lower left corner towards the upper right corner, this branch depicts three leaves akin to those described in the top panel.The third and bottom panel is mainly empty except for the continuation of the branch from the second panel that stretches toward the lower right corner of this panel. Additionally, two leaves similar to those found on branches in the other two panels are visible.The entire drawing utilizes a simple, clean line style, with no shading or color, relying entirely on black outlines on a white background to define shapes and expressions. The elements are cartoon-like with an emphasis on visual clarity and minimalistic detail. There are no background details or additional elements that suggest a specific setting beyond the immediate subjects.
