“…Chicken eggs were not consumed, suggesting that they may be above the upper margin of the size range that can be eaten by hedgehogs. Our results suggest that larger eggs may have a survival advantage, thereby matching those of other studies suggesting that small-bodied mammals are unable to break big eggs (Purger et al 2004) or showing that birds prefer smaller eggs (Montevecchi 1976;Maier and DeGraaf 2000).…”

We tested the hypothesis that the Algerian hedgehog (Atelerix algirus) consumes smaller eggs in preference to larger ones and that the colour of the eggs (brown or white spotted) does not influence the egg consumption rate. Eggs of three galliform species (the quail, Coturnix japonica; the red legged partridge, Alectoris rufa; the chicken, Gallus domesticus) were offered to 14 individual hedgehogs under experimental conditions. Overall, the hedgehogs consumed 107 of the 225 eggs offered (48%) in 5 days. The colour of the eggs did not influence the rates of egg consumption. However, egg size had a significant influence on the rates of egg consumption.Generalized linear mixed models showed that hedgehogs preferred to consume smaller quail eggs (91%, n = 65) than intermediate partridge eggs (44%, n = 110), whereas the largest chicken eggs (n = 50) were not consumed at all. There was a strong inter-individual variation in egg consumption, particularly of partridge eggs, from 0 to 100%, whereas individual variation in consumption of quail eggs was lower, from 70 to 100%.

“…In the morning of 3 April 2006, three brown chicken eggs and a halfsized plasticine egg was placed into each of the nests. Both types of eggs had been stored outdoors for one week prior to the experiment (Purger et al, 2004). A pale orange tape (1 cm wide, 20 cm long) was used for marking the place of each nest (Butler and Rotella, 1998).…”

Nest predation experiment to survey survival probabilities of larger bodied ground-nesting birds (ducks) was carried out on Lake Kuti in May 2006. From 25 artificial ground nests on the floating reedbed islands and 25 nests on the grazed islands, 8 and 1, respectively, were depredated. On the contrary to our expectations, the daily survival rate of artificial nest on the reedbed islands i.e. closed habitats was significantly lower (95.06%) than in the open habitat islands being grazed by sheep and cattle (99.43%). Broken chicken eggs and the marks left behind on plasticine eggs suggested that the predators were probably small mammals and birds. Such predators do not pose serious threat to real nests and clutches, thus they are unlikely to have had significant influence on the dramatic decrease of nesting bird populations in the area.

“…Every nest contained two eggs using one of the following combinations: quail + quail egg (Q + Q), quail + plasticine egg (Q + P) and quail + coated (with PlastiDip w ) plasticine egg (Q + C) of the same size. Artificial eggs were aired for at least two weeks before the beginning of the study (Bayne & Hobson 1997, Purger et al 2004. Coated plasticine eggs remained flexible after drying, so they were able to conserve the marks of predators.…”
