Strategies for Identification

So, you've seen an animal, and you're ready to figure out what it is. Where do you start? Here are several effective strategies that you can use to identify Massachusetts wildlife:

1. Observe Key Characteristics

The first step in identifying any animal is careful observation. Take note of its physical characteristics, behavior, and habitat. The more details you can gather, the better your chances of making an accurate identification. Here are some key things to look for:

Size and Shape: Is the animal large or small? Slender or stocky? What is the overall shape of its body?
Color and Markings: What colors are present? Are there any distinctive patterns or markings, such as spots, stripes, or bands?
Tail: Is the tail long or short? Bushy or slender? What color is it?
Ears: Are the ears large or small? Pointed or rounded?
Legs and Feet: How many toes are visible? Are the feet webbed? Are there claws?
Behavior: How is the animal moving? Is it active during the day or night? What does it seem to be eating?
Habitat: Where did you see the animal? Was it in a forest, field, wetland, or urban area?

By carefully observing these characteristics, you can start to narrow down the possibilities.

2. Consult Field Guides

Field guides are invaluable resources for wildlife identification. These books typically include detailed descriptions, illustrations, and range maps for various species. Some popular field guides for Massachusetts wildlife include:

National Audubon Society Field Guide to North American Mammals: This comprehensive guide covers a wide range of mammals found in North America, including those in Massachusetts. It features detailed descriptions, photographs, and range maps.
National Audubon Society Field Guide to Birds (Eastern Region): This guide focuses on birds found in the eastern United States, including Massachusetts. It includes detailed descriptions, illustrations, and information on bird behavior and habitat.
Peterson Field Guide to Reptiles and Amphibians of Eastern and Central North America: This guide covers reptiles and amphibians found in the eastern and central United States. It features detailed descriptions, illustrations, and range maps.

When using a field guide, start by browsing the sections that seem most relevant based on your initial observations. For example, if you saw a small, brown mammal, you might start by looking in the section on rodents. Compare the animal you saw to the descriptions and illustrations in the guide, paying close attention to key characteristics.

3. Utilize Online Resources

The internet offers a wealth of resources for wildlife identification. Many websites and apps provide information, photos, and videos of different species. Here are some helpful online resources:

iNaturalist: This website and app allow you to upload photos of plants and animals and get help identifying them from a community of naturalists and experts. It's a great way to get feedback on your observations and learn from others.
Massachusetts Division of Fisheries and Wildlife (MassWildlife): The MassWildlife website provides information on Massachusetts wildlife, including species profiles, habitat information, and conservation efforts. You can also find contact information for local wildlife experts who may be able to help with identification.
All About Birds (Cornell Lab of Ornithology): This website is a comprehensive resource for bird identification, featuring detailed information, photos, and sound recordings for hundreds of bird species.

When using online resources, be sure to compare information from multiple sources to ensure accuracy. Keep in mind that online information may not always be up-to-date or complete.

4. Seek Expert Assistance

If you're still stumped after consulting field guides and online resources, don't hesitate to seek help from experts. There are many individuals and organizations that can assist with wildlife identification:

Local Nature Centers and Museums: Many nature centers and museums have naturalists on staff who can help identify animals. They may also offer programs and workshops on wildlife identification.
Wildlife Rehabilitators: Wildlife rehabilitators are trained to care for injured and orphaned animals. They often have extensive knowledge of local wildlife and can help with identification.
MassWildlife District Offices: MassWildlife has several district offices throughout the state. You can contact the office in your area for assistance with wildlife identification.

When seeking expert assistance, be prepared to provide as much information as possible about the animal you saw, including its physical characteristics, behavior, habitat, and the date and location of the sighting. A photo or video can also be very helpful.

5. Consider Similar Species

Sometimes, the key to identification lies in distinguishing between similar species. Many animals share similar characteristics, making it challenging to tell them apart. For example, several species of small brown birds can be found in Massachusetts, and it may take careful observation to distinguish between them. When you've narrowed down the possibilities to a few species, take the time to compare their key characteristics side-by-side. Look for subtle differences in size, color, markings, and behavior. Range maps can also be helpful, as some species may be more common in certain areas than others.

Common Identification Challenges

Wildlife identification isn't always easy. Several factors can make it challenging to identify animals accurately. Here are some common challenges:

Poor Visibility: If you only get a brief glimpse of an animal, it can be difficult to gather enough information for identification. Poor lighting conditions or dense vegetation can also hinder visibility.
Similar Species: As mentioned earlier, many species share similar characteristics, making it challenging to tell them apart.
Seasonal Variations: Some animals change their appearance depending on the season. For example, birds may have different plumage in the breeding season than in the winter. Mammals may have thicker fur in the winter than in the summer.
Juveniles: Young animals may look different from adults, which can make identification difficult.
Hybridization: In some cases, animals may hybridize, creating individuals with characteristics of both parent species. This can make identification very challenging.

If you encounter any of these challenges, don't get discouraged. Keep practicing your observation skills and using the resources available to you. With time and experience, you'll become more adept at identifying Massachusetts wildlife.

Specific Examples and Scenarios

To illustrate the identification process, let's consider a few specific examples and scenarios:

Scenario 1: You see a small, furry animal with a bushy tail running across your lawn.

Step 1: Observe Key Characteristics: The animal is small and furry with a bushy tail. This suggests it's likely a mammal, possibly a rodent or a small carnivore.
Step 2: Consult Field Guides: You consult a field guide to mammals and find several possibilities, including gray squirrels, red squirrels, and chipmunks.
Step 3: Compare Characteristics: You compare the characteristics of these species and note that gray squirrels are larger than red squirrels and chipmunks. You also notice that gray squirrels have predominantly gray fur, while red squirrels have reddish fur and chipmunks have stripes. The animal you saw was gray and larger, so you conclude it was likely a gray squirrel.

Scenario 2: You hear a bird singing a complex song in the woods.

Step 1: Observe Key Characteristics: The bird is singing a complex song, suggesting it's likely a songbird. You try to get a visual sighting of the bird, but you're unable to see it clearly.
Step 2: Utilize Online Resources: You use an online bird identification resource that allows you to search by song. You describe the song and listen to recordings of different bird songs until you find one that matches. The recording matches the song of a wood thrush.
Step 3: Confirm Identification: You consult a field guide to birds and read about wood thrushes. You learn that they are known for their beautiful, flute-like songs and that they are commonly found in Massachusetts forests. This confirms your identification.

Scenario 3: You find a snake in your garden.

Step 1: Observe Key Characteristics: The snake is slender and has smooth scales. It's brown with dark blotches along its back.
Step 2: Consult Field Guides: You consult a field guide to reptiles and amphibians and find several possibilities, including garter snakes, milk snakes, and copperheads.
Step 3: Consider Safety: You know that copperheads are venomous, so you exercise caution. You compare the markings of the snake you saw to the illustrations in the field guide and note that it doesn't have the hourglass-shaped markings of a copperhead.
Step 4: Seek Expert Assistance: To be certain, you take a photo of the snake and send it to a local wildlife expert. The expert confirms that it's a garter snake, which is non-venomous.

These examples illustrate how you can use a combination of observation, field guides, online resources, and expert assistance to identify Massachusetts wildlife.
