Hemophilia, von Willebrands Disease, or any other bleeding disorder?
No problem! Fly into this fine-feathered hike and game for fun physical activity!

By Jill Squire, The Birding Nurse

Combining hiking, birdwatching, and a scavenger hunt in a local park or nature reserve creates an entertaining, lively, and enriching activity for friends and family.

Hiking on local, beautiful outdoor trails is a choice activity, a safe and popular sport for those with bleeding disorders 1. You can turn your invigorating birdwatching hike into a fun, full-fledged (pun intended) scavenger hunt game with friendly competition appropriate for all ages.


Western Pennsylvania is rich with public hiking trails where people of all ages can enjoy the sights and sounds of many fascinating, lively species of birds, including migrating birds. Hiking scavenger hunters may be fortunate enough to spot a majestic hawk, owl, or eagle.

The free phone app Merlin Bird ID by Cornell University adds wonder and magic to the day. Merlin Sound ID, a feature of Merlin Bird ID, recognizes the calls of over 540 species of US birds. It is entertaining to watch Merlin Sound ID work its magic as it listens to bird calls and a list of the birds it senses starts to appear.

And who does not like seeing the world through binoculars?

Birds have fascinating personalities and abilities, adding to the enjoyment. They tend to show just the barest glimpses of themselves and are not known to ham it up by posing, adding to the game’s challenge; Chickadees are the exception, often found front and center.

Birds will hop to another branch when you have them in your binocular sights to show another hiker–birds are fickle that way.

Chickadees are gregarious and will chatter away with you, flittering from branch to branch at eye level, sometimes sounding like angry Volkswagen Beetle car horns.

House finches may make you laugh out loud by calling like high-pitched squeeze toys. There are so many personalities to enjoy in birds.

You, your significant other, family, and friends can have a fabulous, fascinating, fun hike while finding birds and learning their calls. You may even catch sight of some rare finds! Merlin Bird ID will tell you if your bird is a rare sighting.

The list Merlin Sound ID creates as it senses bird calls sets up the perfect scavenger hunt. You don’t even have to hide anything! Merlin and the birds do it for you!

Recommended items to make the most of your bird-call scavenger hunt:

  • a public park or nature reserve with a combination terrain of woods, fresh water, meadowlands, and easy-to-navigate paths (there is a list of recommended places at the end of the article)
  • walking sticks – which can be as simple as sturdy sticks from your backyard
  • binoculars, at least one pair for each team, or one pair per person (decent binoculars are available for around $30)
  • the free Merlin Bird ID phone app from Cornell University
  • paper and pen to keep score for each team, or “Notes” on a phone
  • water or sports drinks for hydration
  • the proper footwear for safe and comfortable walking
  • pack with personal supplies such as factor, ace bandage, large gauze pads, a whistle, snacks, an extra shirt
  • trail map for the large park or reserve
  • snacks if planning a hike longer than two hours

You have an almost guaranteed fail-safe day for great memories right at your toe-tips!

A quick note on binoculars (that may cause binocular purists to wince)

You can find a decent pair of binoculars in the store or on various sites, such as Walmart, Target, or Amazon, for as little as $30.00. Look for a pair that rates high in reviews for clarity and includes “birds” or “birdwatching” in their description. There are better quality binoculars to satisfy the purists at a higher price. The less expensive binoculars are typically sturdy, intended for fun, and perfect for kids to use without fear of knocking them about a bit.

Bountiful benefits for those with bleeding disorders

You can grasp this opportunity to discover new parks, engage in health-preserving exercise, learn amazing bird facts, and enjoy a relaxing activity that will divert your mind from stress 5.

For those with hemophilia or von Willebrand’s Disease, exercise is central to maintaining health by keeping joints in good condition, burning calories, and strengthening muscles for improved well-being. 4 Exercise also helps to prevent injury by developing stronger muscles to support movement, and decreases the chances of bleeding by organically increasing factor VIII and VW Factor levels. 2,3

Steps for Living 4 recommends three types of exercise and activity for those with bleeding disorders to work toward optimal body health:

  • strength training
  • aerobic exercise
  • balance and flexibility training

Hiking meets all three of these recommendations 5! Added bonuses are that you don’t need to pay for a gym membership and can enjoy time with family or friends!

Using the quadriceps muscles when hiking on hills increases strength and helps to maintain bone density. Navigating obstacles on the ground enables you to improve your balance. You burn calories while hiking without putting too much strain on your joints. Time in the refreshing green space of the woods has the added benefits of improving sleep and reducing anxiety and depression. Kampert expertly reviews all of this in the 9 Benefits of Hiking5.

How to enjoy the scavenger hunt game with birds and Merlin Bird ID

These directions are less complicated than they look. They are a combination of instructions for playing the scavenger hunt with the birds as prey (you may have Birds OF Prey on your scavenger hunt list!) and instructions for using the free Merlin Bird ID app for the scavenger hunt game.

First, decide on your group size

  • decide on your team size: individual people, small teams – such as a child and adult paired, or groups, or just your one group as a family or couple’s outing
  • define a length of time over which the scavenger hunt will take place, such as 30 minutes
  • at least one person on each team should have a phone with the free Merlin Bird ID app
  • each team needs a scorekeeper to record the birds found by themselves and their team membersTo start
  • all players stand quietly together while the phone users run Merlin Sound ID to record the bird calls for about two minutes and watch the marvel of Merlin Sound ID8 work its magic
  • as Merlin Sound ID senses a bird call, Merlin will give the bird call its best match to a bird species and magically list the bird species
  • once the red “stop” button is hit, the recording will stop, and the list of birds Merlin Bird ID sensed will be saved – note the recording is date and time-stamped
  • compare the lists among phones to check that they are similar; the lists do not need to be exact matches, as the main purpose is to have fun (if they are way off, record again to have a fairly level playing field)
  • the scorekeeper creates their list from the Merlin Sound ID matches

Teammates – obtain and learn your scavenger hunt birds

  • while comparing Merlin Sound ID results, note that each bird listed has a small image of the bird, and there is a dropdown arrow
  • select a dropdown arrow
    1. a list of recordings of various calls the bird makes appears
    2. at the bottom of the calls list is a details selection; press this to see several images of the identified bird: male, female, juvenile, and more
    3. information appears bout favorite bird habitats where players will most likely spot the bird, such as high in the tree canopy, low-lying brush, reeds by a pond, or tall meadow grasses
    4. let everyone on the team see these pictures and bird habitats
  • team members can take screenshots of the scorekeeper’s list or the Merlin Sound ID list

Have fun on the scavenger hunt!

  • now, using the binoculars, the list of birds Merlin ID’d, along with their photos and information about their favorite habitats, find those birds
  • if team members have Merlin Bird ID on their phone, they can run Merlin Sound ID to hone in on the birds on the list – it’s pretty spectacular to watch Merlin Sound ID in action
    1. avoid playing bird call recordings, as they can disrupt the birds and create unintended consequences 9
  • as a team spots birds on the game list, the team scorekeeper records the visual bird IDs
  • your team is now working down your scavenger hunt list
    1. the birds will chatter and hide, adding to the challenge and fun
    2. the thrill of victory when they are spotted is contagious

And the winner is…

  • at the end of the allotted time, the teams gather in the original starting area and compare lists to see which team visually identified the most birds on the scavenger hunt game list
  • consider adding to the fun with teams picking outrageous names for themselves, such as Fabulous Finches or T-Rex Chickadees (birds are dinosaurs!)

Some notes (pun intended) on hiking and finding birds

The more you use Merlin Sound ID, your ear for bird calls will improve. After a few outings, you might be surprised by what you can recognize.

Feel free to adapt this game, birdwatching and hiking, to whatever works for you. The point is to get outdoors and have fun; learn about our fine-feathered friends while enjoying a good hike and beautiful local resources.

It is important enough to share again that Earth and Sky published an article about a study showing that bird song recordings can harm birds. It is vital to avoid playing bird calls around the birds, as there is a risk of unintended consequences, such as a bird leaving behind a nest 9.

Keep it safe

The day and memories will be more fun through the effort to keep it injury-free and preparation for the unexpected. This effort is vital for everyone, particularly those with bleeding disorders.

Here are some simple measures to take: 1, 5

  • watch your path for tripping hazards while moving
  • avoid walking while looking up into the trees
  • avoid sudden stops with people directly behind you; instead, step to the side
  • avoid steep paths with steep inclines and a lot of loose debris
  • use a walking stick to help maintain balance
  • wear the right shoes for the terrain
  • apply sunscreen to avoid sunburn
  • check the weather and dress appropriately
  • let someone else know where you are going
  • have at least three people on the hike in case of injury: one to stay with the injured person, one to go for help
  • pack personal supplies such as factor, a whistle, snacks, an extra shirt
  • hydrate well before, during, and after your hike to prevent dehydration and sore muscles

Treating sore muscles and minor injuries 10,11

  • avoid taking ibuprofen, naproxen, aspirin, or other non-steroidal anti-inflammatory medications
  • if cleared by your doctor, acetaminophen (Tylenol) can help with discomfort
  • use Rest Ice Compression and Elevation, or the RICE protocol, for minor injuries
  • if swelling, pain, numbness, or other discomfort continue, consider evaluation for a bleed by your Hemophilia Treatment Center or hematologist
  • avoid ignoring possible bleeding; contact your Hemophilia Treatment Center or hematologist if you have an injury and suspect a bleed into your joint or muscle – protecting joint health is essential
