Understanding Crow Calls: The Language of the Corvid
The sharp “caw” of a crow, echoing through the fields or woodlands, is a familiar sound. Whether you’re a dedicated hunter, a passionate birdwatcher, or someone simply fascinated by the intelligent corvids, understanding how to call crows can be an incredibly rewarding skill. While commercially produced crow calls are readily available, there’s a unique satisfaction – and a considerable cost saving – that comes from crafting your own. This article delves into the art of crafting a *crow call*, providing comprehensive, DIY instructions for both beginners and experienced enthusiasts. We’ll explore the fundamentals, different construction methods, and techniques to master this fascinating craft, empowering you to communicate with these captivating birds.
The world of avian communication is complex, and the crow is no exception. They utilize a wide repertoire of calls, each conveying a different message. Before diving into construction, let’s examine the essence of what makes a successful crow call effective.
Crows, with their remarkable intelligence and social structures, employ a complex system of vocalizations. Understanding these calls is key to attracting them, whether for hunting, observation, or simply the joy of listening. A *crow call* isn’t just a noise; it’s an attempt to mimic a specific message within their language.
There are generally three categories of calls, though they exist on a spectrum, and variations are plentiful. First is the basic “caw” – the everyday communication call. It might be a greeting, a confirmation of presence, or simply a signal. Second, are alarm calls, usually a rapid succession of “caws” – indicating a threat or danger. Finally, there are distress calls, which sound desperate and are often highly effective at attracting crows, particularly those looking to investigate.
Why do *crow calls* work? Crows are incredibly social and curious creatures. The sound of another crow – or what they perceive as another crow – often piques their interest, drawing them in to investigate. Social hierarchy and the instinct to protect the flock play a significant role in how crows respond to calls. The distress call, for example, triggers a protective response, as crows converge to help a member of their colony. By mimicking these sounds, we tap into their natural behavior and increase the likelihood of attracting their attention. Choosing the right sound is vital to achieve your desired effect.
Types of Crow Calls: Mouth-Blown vs. Other Techniques
Before getting into building, it’s worth mentioning the different methods of making a *crow call*. It can give you an idea of the various methods and the range of sounds possible.
The most common type of *crow call* is a mouth-blown device, often using a reed or vibrating element to produce the sound. These are usually compact, easily portable, and relatively simple to operate. They can be further split into diaphragm calls, where you manipulate a vibrating membrane with your mouth, and reed calls.
Then there are bellows-type calls. These create sound by squeezing a chamber filled with air. These are generally less popular for recreational purposes, but are found in digital callers. Digital callers, use recordings and amplification to reproduce the calls. However, since this article focuses on the DIY process, we’ll concentrate on the hand-crafted methods.
The most effective calls are the ones you learn to use well, and can get the sound as close to a real crow as possible.
Method 1: Building a Simple “Wooden” Call
This method is ideal for beginners, using readily available materials and requiring minimal tools. The “wooden” crow call is a surprisingly effective option that captures the basic “caw” sound.
Materials Needed:
- A wooden dowel: Ideally, around 0.75-1 inch in diameter and 4-6 inches long. Hardwoods, like oak or maple, work well, but softer woods are usable.
- A thin rubber band: The size should be appropriate to fit snugly around the dowel.
- A sharp knife or utility knife: For shaping and cutting.
- Optional: Fine-grit sandpaper and paint or stain (for finishing).
Step-by-Step Construction:
- Preparing the Dowel: The dowel is the sound chamber. Ensure the ends are cleanly cut. If the ends are rough, lightly sand them. The key to a quality sound is a good shape.
- Creating the Sound Chamber: Hold the dowel horizontally, one end facing towards you. Using the knife, carefully shave a slight bevel or angle on the end. A gentle slope of around 1/4 inch at most, with the wood removed. It’s important that this edge is clean. This is where the sound will originate.
- Adding the Rubber Band: Place the rubber band near the beveled end of the dowel. The rubber band should be able to vibrate freely when the call is blown into. It should be taut to provide a good tone.
- Testing and Adjustments: Bring the beveled end of the dowel to your lips, and blow across the bevel, as you would with a reed instrument, to get a sound. Adjust the placement of the rubber band (tension) to change the pitch. Experiment with different amounts of air. Listen to the sound of the crow calling, and try to mimic the sound.
- Finishing Touches: (Optional) You can lightly sand the entire dowel to remove any splinters. Apply a coat of paint or stain to protect the wood and give your *crow call* a more refined appearance.
This method is simple, and can be adjusted to produce a deep, reverberating “caw.”
Method 2: Constructing a PVC Pipe Call
This method provides a more robust and durable *crow call*. PVC pipes are inexpensive, easily obtained, and can be molded to give a wide array of sounds.
Materials Needed:
- PVC pipe: Around 1-1.5 inch diameter, with the length between 5 to 8 inches, gives a good balance of sound and portability.
- Reed Material: This is the vibrating component. Options include thin plastic from food packaging, mylar sheets (available at craft stores), or even thin strips of a durable material.
- Rubber bands or tape: For securing the reed.
- Sharp knife or utility knife or PVC cutter.
- Optional: PVC glue.
Step-by-Step Construction:
- Cutting the PVC Pipe: Cut the PVC pipe to your desired length. Ensure the cuts are clean and square. A PVC pipe cutter makes this task easier, though a saw can be used with caution.
- Creating the Sound Chamber: On one end of the pipe, carefully shape the rim to accommodate the reed. The rim can be slightly beveled inward, and should create a smooth surface for the reed to rest on. It is important to remove the rough edge.
- Attaching the Reed: Place your reed over the shaped opening. Use rubber bands or tape to firmly secure the reed to the end of the pipe. The reed should be held tightly enough to vibrate, but not so tight that it mutes the sound.
- Testing and Adjustments: Bring the reed end of the *crow call* to your lips. Blow across the reed to generate a sound. Adjust the tension of the reed (by moving the rubber bands or tape) to fine-tune the pitch and tone. You may need to experiment with the size, shape, and material of your reed to find the best sound.
- Optional: Assembly: For a more permanent and sealed construction, apply PVC glue to secure the reed and the edges. This prevents air leaks, and it can also improve sound quality. This step will make it harder to adjust the reed, so adjust it first.
The PVC method is a good way to craft a durable and effective *crow call* that is sure to provide excellent results.
Tuning and Refining Your Crow Call: Getting the Perfect Sound
No matter which method you choose, the process of tuning your handmade *crow call* is crucial. It involves adjusting the various components and experimenting with blowing techniques to achieve the desired sound quality.
Tuning Techniques:
- Adjusting Reed Tension (For Wooden or PVC Calls): This is the most common adjustment. Tighter reed tension usually raises the pitch, while looser tension lowers it. Move the rubber band (for wooden calls) or the tape (for PVC calls) to alter the pressure on the reed.
- Experimenting with Blowing Techniques: Vary the angle and force of your breath as you blow across the reed. You can get a higher-pitched sound with a sharp blast and a lower tone with a softer puff. Listen closely to recordings of crows. You are trying to match the range, and the characteristics of the sound.
Practice Makes Perfect:
- Listening to Recordings: Listen to recordings of real crow calls to familiarize yourself with their distinct vocalizations.
- Practicing Basic Calls: Start with the simple “caw.” Try to mimic the sound as accurately as possible. Then, branch out to more complex calls.
- Varying Your Calls: Crows don’t just produce one sound. Learn to control the range, duration, and pitch of the sounds to attract your target.
Tips for Successful Crow Calling: Location and Technique
Once you’ve mastered your *crow call*, the next step is employing it effectively. The success of your calling session depends on several factors.
Finding the Right Location:
- Scouting the Area: Before going out, scout your hunting grounds. Look for crows in the area, identify their flight patterns, and note potential roosting locations.
- Concealment is Key: Hide yourself. Crows have excellent eyesight, and they will spot movement or any unnatural appearance. Utilize natural cover, or use camouflage.
- Wind Direction: Position yourself so that the wind is in your face, and blowing your scent away from the incoming crows.
Effectively Using Your Call:
- Start Slow: Begin with a few basic “caw” calls to gauge their response.
- Mix It Up: Use a variety of calls to mimic different situations – alarm, distress, etc.
- Be Patient: Crows may take time to respond. Don’t give up too soon. Keep a patient and steady rhythm.
Safety First
Always be aware of your surroundings, and adhere to local hunting regulations, if applicable. Always be respectful of the environment, and your target species.
