*2. Bird Anatomy*

> **2a.** Sketch or trace a perched bird and then label 15 different parts of the bird.

Knowing the parts of a bird is like knowing the positions on a soccer field — it gives you a shared language to describe what you see. When you spot a bird and want to identify it or describe it to someone else, you need to know whether that flash of color was on the bird's **crown**, its **nape**, or its **rump**. This requirement builds that vocabulary.

## The 15 Parts You Need to Know

Here are the major external parts of a perched bird. You will sketch or trace a bird and label at least 15 of these:

### Head Region

- **Crown** — The top of the head. Many species have distinctive crown colors or patterns (think of the Ruby-crowned Kinglet's hidden red patch).
- **Forehead** — The area between the base of the bill and the crown.
- **Nape** — The back of the neck, just below the crown. Some warblers have distinctive nape patterns.
- **Eye ring** — A ring of color (often white or pale) surrounding the eye. This is a key field mark for many species.
- **Lore** — The small area between the eye and the base of the bill. Dark lores can give a bird a "masked" appearance.
- **Chin** — The small area directly below the bill.
- **Throat** — Below the chin, the front of the neck. Many birds have brightly colored throats (like the Ruby-throated Hummingbird).

### Bill

- **Upper mandible** — The top half of the bill.
- **Lower mandible** — The bottom half of the bill.

Bill shape is one of the most important clues for identifying a bird's diet and family group. You will explore this more in Requirement 6.

### Body

- **Breast** — The upper front of the body, below the throat. The American Robin's orange breast is one of the most recognized field marks in North America.
- **Belly** — The lower front of the body, below the breast.
- **Flanks** — The sides of the body, between the breast/belly and the wings.
- **Back** — The upper surface of the body between the wings.
- **Rump** — The lower back area, just above the tail. The Yellow-rumped Warbler gets its name from this feature.

### Wings and Tail

- **Wing bars** — Pale or colored stripes across the folded wing, formed by the tips of the wing coverts. Many species have two wing bars.
- **Tail** — The fan of feathers extending behind the body. Tail shape (forked, rounded, squared) is a useful field mark.

### Legs and Feet

- **Tarsus** — The lower leg (the visible "leg" of a perched bird, which is actually equivalent to your foot and ankle).
- **Toes** — Most perching birds have three toes forward and one back, an arrangement called **anisodactyl**.

> What looks like a bird's knee bending backward is actually its ankle. A bird's true knee is hidden up near its body, tucked under the feathers. The long, visible section of "leg" is really the tarsus — the equivalent of the top of your foot.

## Tips for Your Sketch

You do not need to be an artist to complete this requirement. The goal is to learn where each part is located, not to create a museum-quality drawing. Here are some tips:

**Sketching Success** — Follow these steps for a clean, labeled drawing

- [ ] Find a reference image: Use a clear side-view photo from a field guide or the Cornell Lab website.
- [ ] Trace or sketch the outline: Focus on the overall shape — head, body, tail, legs.
- [ ] Add major features: Bill, eye, wing, tail feathers.
- [ ] Label each part: Use lines that point clearly to each feature, and write the name at the end of each line.
- [ ] Include at least 15 labels: Choose from the list above.
- [ ] Keep labels on one side if possible: This keeps the drawing clean and readable.

> **Tip**

> If you are tracing, look for a side-view silhouette or outline drawing of a perched songbird. The Cornell Lab's "All About Birds" website has excellent reference images for nearly every North American species.

Now that you know the parts of a perched bird, it is time to zoom in on the wing and learn the different types of feathers.
