Why Use Thermal Imaging for Wildlife Observations?

Thermal cameras are indispensable tools for detecting and locating animals in various environments. They are especially useful for:

  • Nocturnal Surveys: Many animals, such as bats and hedgehogs, are active at night. Infrared cameras for wildlife allow you to monitor these creatures without disturbing their natural behaviour.
  • Dense Foliage: Infrared cameras can detect heat signatures through thick vegetation, making it easier to find animals in trees and hedgerows.
  • Building Surveys: Thermal imaging for wildlife observations helps locate animals in buildings, whether they are roosting bats, nesting birds or hidden hives, by identifying heat patterns.
  • Health Assessments: species of both animals and plants can be checked non-invasively for ailments and from a safe distance using thermal cameras.

Thermal Imaging for Wildlife Observations: Ecology & Conservation Applications

  • Bat Surveys: Use a thermal monocular, such as the Guide TK612, to detect bats emerging from roosts in buildings, trees, and caves. A wide-angle lens makes it easier to monitor multiple exit points simultaneously, ensuring no bat goes unnoticed.
  • Bird Monitoring: Observe nesting birds in dense foliage or high tree canopies. High-resolution IR imaging helps in identifying individual birds and monitoring their behaviour without causing disturbance.
  • Reptile Research: Locate reptiles that are camouflaged in their natural habitats. Thermal imaging can reveal heat signatures of reptiles hiding in leaf litter or within dense vegetation.
  • Hedgehog Tracking: Track hedgehogs at night as they move through gardens, hedgerows, and fields. The TK612’s precise 10° lens helps in pinpointing the exact location of these small nocturnal mammals.
  • Wildlife Rescue: Assist in wildlife rescue operations by quickly locating injured or stranded animals in challenging environments, such as dense underbrush or urban areas at night.

  • Monitor Species Population: Assess the success of conservation and/or re-wilding efforts by using thermal imaging to track and monitor the population sizes of protected species. Thermal cameras can detect slight temperature differences across a scene making it easy to spot endangered species in foliage, trees, hedgerows, fields, and urban environments.
  • Relocating Protected Species: Occasionally, important species, such as bees, make their hives in our homes. As the heat generated by the working bees is detected and illustrated by thermal cameras, this makes pinpointing hives and safely relocating them easy.
  • Assess Tree Health: Thermal cameras map the heat distribution across an object or scene. This means they detect cold spots as well as hot spots. Cold spots on trees can indicate health issues such as cavities or decaying tissue. As thermal imaging provides a non-invasive method of assessing tree health, it does not compromise the trees’ defences or disturb wildlife.

The Guide TK612 Thermal Monocular: An Ideal Choice

Guide TK612 Gen2 Thermal Imaging Monocular

The Guide TK612 Thermal Monocular is specifically recommended for ecology and conservation applications. Here’s why:

  1. Wide-Angle Lens: The TK612's wide-angle lens delivers a broader field of view. This feature allows ecologists and conservationists to survey large areas more quickly and thoroughly, whether it's a building, tree canopy, or hedgerow. You can detect and observe animals like emerging bats or birds in greater detail, enhancing your ability to monitor wildlife effectively.
  2. High-Resolution IR Imaging: With a 640 x 480-pixel infrared resolution, the TK612 provides sharp and clear thermal images. This high resolution ensures that you can see fine details of the animals and their surroundings, making it easier to identify species and behaviours.
  3. 10° Lens for Precision: The 10° lens of the TK612 offers a focused view, which is particularly beneficial when you need to observe specific areas or small animals. This precision allows for detailed monitoring of wildlife habitats and behaviours, making your research more accurate.
  4. 16GB Memory: Equipped with a substantial 16GB internal memory, the TK612 allows you to store extensive amounts of thermal imaging data. This is especially useful for long field sessions where you need to record and review your observations later.
  5. HDMI Output: The HDMI output feature enables you to connect the TK612 to external displays. This is perfect for group observations, presentations, and detailed analysis on larger screens.
  6. Economic Price Point: Despite its advanced features, the TK612 is economically priced. This makes it accessible for both individual researchers and larger conservation organisations, providing excellent value for money.

Guide TK612 Thermal Monocular Customer Testimonial

"I jumped at the chance to get a 10mm Guide TK612 thermal scope because I already own a 19mm Guide Track 19 and although I am very happy with its quality, its narrow field of view is a real drawback when surveying buildings as you need to position it really far back which is often impossible. I love how much of the building I can now get in the new 10mm [TK612] scope and the [following] photo shows a comparison between the two that I did by positioning the scopes side by side looking at the same building. You can see the 19mm only gets the corner in whereas the 10mm gets almost the whole building in. This will save so much time because I just have one camera to set up and 1 set of footage to review instead of two sets - it's a game changer!" ~ Jean Oudney, Myotis Bat Ecology
