Count cattle in a field from a photo

Counting cattle in a pasture, a pen or at the feed fence

Morning headcounts, moving a herd between paddocks and checking a load against the movement record are the jobs where a photo count helps most. Cattle spread out on pasture and bunch in pens, so the viewpoint matters more than the camera: a gate platform, loading ramp, hillside or drone pass shows backs instead of a wall of heads. In a barn, the feed fence is the best spot, because animals line up side by side while they eat.

Calves standing behind cows, animals lying down in long grass and cattle in the shade of trees are the usual misses. Black and dark red coats on dark ground lose their outline in low evening light, so earlier in the day often gives better contrast. For a large pasture, use fence lines or water troughs to split it into sections, photograph each section once and add each as a tally row, making sure no group of animals falls into two frames.

Look at every dot before using the total, and confirm any shortfall by walking the field: a photo count is a draft, not proof that an animal is present or missing. A mixed group of cattle, sheep and goats can be counted on the livestock counter with one example per species, sheep flocks need slightly different handling, and the bales left for winter feed can be tallied with the hay bale counter.

Choosing the moment and the viewpoint

• A raised point that looks down on backs rather than across at heads
• Feeding time at the fence or bunk, when cattle stand side by side
• Fence lines used to divide a big pasture into separate frames
• Calves and animals lying down checked by eye after the count
