Hedgehogs are widely known to attack and consume the chicks of birds if they encounter a nest. Unfortunately, it is difficult to separate active predation from scavenging when dealing with stomach and faecal analyses. Before we look at the data, it is worth taking a moment to consider why hedgehogs would want to eat eggs in the first place. Eggs have long been identified from the stomach analyses of hedgehogs, although many hedgehog enthusiasts have argued that this is perhaps to be expected, given that egg is commonly the bait in traps used to catch hedgehogs.
Indeed, whether or not hedgehogs are interested in, or capable to gaining entry to, birds’ eggs has been a subject of much conjecture and argument. The contents of broken hen and pigeon eggs are licked up, but most hedgehogs seem to have no particular preference for them. Proceedings of the Zoological Society of London during 1951. He hit it sideways with his sharp canine teeth, and made a hole in it just big enough to thrust in his little black nose, and then with his tongue licked out the contents, and mightily he seemed to enjoy it, little thinking what evidence he was giving against the rest of his species. I found the shell with a piece the size of a shilling broken out of one side, and the contents clean gone. The next questions we arrive at are: how often do eggs occur in the diet of hedgehogs?
Kruuk found that hedgehogs could damage an average of 4. 5 eggs per night, kill an average of 2. 1987 suggested — based on tooth puncture marks — that hedgehogs were responsible for losses from two wader clutches. It should be mentioned that low percentages in the diet does not necessarily correlate with impact on the population. Where nest predators are commonplace and the nesting species relatively rare, small percentages per hedgehog diet can soon add up to cause an issue. Furthermore, the number of eggs in the diet is likely to be considerably underestimated.
At locations where hedgehogs have been introduced, there is little doubt that they can have a considerable impact on some local bird populations. In their native environs, however, the damage they cause is a matter of debate. North Ronaldsay and the Uists, which I will briefly summarise here. 1972, when a postman brought over three animals to keep in his garden in the hope that they would control garden pests.
The failure of breeding in the bird colonies was observed on other islands where there were no hedgehogs. It was actually due to collapse of the sand eel population upon which the birds feed, nothing to do with hedgehogs. The estimates of eggs in the diet from faecal analyses are probably lower than the reality, because nest predators often break the shell and eat the yolk and albumen. Overall, the data and models presented by Jackson and his co-workers suggest that, without intervention, hedgehogs will probably cause the extinction of dunlin on the island and lead to significantly reduced populations of redshank and snipe.
