Bird Talons: Why Is It Useful for Birds Of Prey?

Talons are the long, sharp hooked claws or nails of a bird and most prominently a raptor. At the end of bird’s every toe, there’s one talon. Depending on talon’s use to bird and how worn they are, the talons vary in shape and size.

Raptors like hawks, eagles, falcons and owls have thicker, sharper and much enlarged talons than other birds. These birds of prey use their fierce talons for catching and dismembering their prey. They are strong enough to clasp the prey until it cuts to the mortal wound.

What All Can Birds’ Talons Do?

Even though talons are mostly associated with raptors, all birds have talons. The birds use their talons for individual needs and various purposes. Let’s know about some of the common ways how birds use their talons.

• To dig out a nesting burrow or a scrape nest or alter the present nest structure
  
• To mount trees while hunting for food especially in the case of woodpeckers, creepers and nuthatches
  
• To preen the areas that can’t be reached with the bird's beak (like nape or head)
  
• To itch at the insects inside the feathers or on bare part of skin
  

• To clasp a surface tightly while being perched and avoid losing balance in windy weather 
  
• To carry different items such as nesting material, food or prey
  
• To hold the food while eating like cracking nuts or large seeds 
  
• To move the eggs tenderly at the time of incubation for even heat distribution
  

The aggressive birds use their talons like a weapon for attacking the predators, intruders and the rival birds competing for food, mates or territory. They may also use talons for defending their mate or nest when they’re under threat.

A Birder Can Identify A Bird By Looking Closely At Their Talons

Made of keratin, a bird’s talons grow throughout its lifespan. Talons begin to worn out and lead to malformed talon in rare cases. Talons’ thickness, curvature and vary for every bird species  and could even be used for identification in some cases. So whenever talons are noticeable, bird-watchers should carefully notice these things. 

• Look at the talons’ color and see if they change in color along their length or they have a contrasting color to that of a toe or webbed foot. However, talons’ color may not be accurate due to staining, light conditions and angle of viewing.
  
• Observe the bird’s overall claw length in comparison to the size of foot. Birds such as jacanas have really long talons that help them in balancing on lily pads and unsteady marsh surfaces. Also pay heed to every talon on a bird's foot to make sure they all show same characteristics and notice which talon is boldly different.
  
• Notice the claw curvature especially if the talons appear too curved. Birds climbing up and down tree trunks on a regular basis often have more curved claws giving them firmer and more stable grip on irregular or broken surfaces.
  
• Check out for the overall talon thickness especially in comparison to its toe. Birds having really thick and strong talons tend to be more efficient birds of prey and they hunt using their talons as lethal weapons.
