Abstract:
The spur-winged lapwing (Vanellus spinosus L.) range throughout most of Africa, the Middle East (Israel, Lebanon, Iraq, Syria etc.) and only the eastern part of the Mediterranean (Turkey and Greece) in Europe. These rare birds for Europe and Turkey have an important population size in this region. Turkey lies on the migration route for many species of migratory birds and for this reason is very important for studies of stopover and breeding ecology. Spur-winged lapwings are a summer visitor for our country and also breed here. Boğazkent/Antalya represents one of the primary breeding areas in Turkey. We aimed to determine population crowded, habitat selection predators and negative impacts about breeding of this species in Boğazkent.
Materials and Methods:
This study have been done breeding periods. Observations started beginning of March twice or three times a week to determine the migration phenology. Beginning of April continue to observations (Figure 1 and 2) their breeding behaviours. April, May and June were breeding periods. Adults were catched on their nests after finding nests (Figure 3). We determined clutch size and hatchling number. We banded 39 individuals with metal and colour ring in three years (Figure 4 and 5). Futhermore we determined, it’s habitat selection for breeding.

Conclusion:
The predation risk is very high during both breeding and feeding periods. Their nesting on ground and hatchling also always ground therefore they clear predation (Figure 9 and 10). Especially hatchlings mortality is veri high. Human activities, specially plough of the fields affect the destruction of the nests or pairs leave the nests. On the other hand hooded crow, dogs and fox are the most predators (Figure 11). Spur-winged lapwing is under threaten and breeding areas of its must be protected. Probably to protect and to raise the breeding success, the preventions must be executed against to predators and also during ploughing may be people much more carefully.

Results:
Between 2009 and 2012 (only data used from for measurement) In birds (26 pairs), in birds (30 pairs), in birds (36 pairs) and in birds were counted (Figure 6). In addition to, in nests, in nests , nests and nests were found. We also observed banded individuals from last year in the same breeding area. Clutch size was generally 4, but also 2, 3 or 5 eggs (only 2 nests). We observed 10 hatchling in 2009, 23 hatchling 2010 and 18 hatchling Hatchling number is lower because predation factor is very high in Boğazkent. Specially predators is hooded crow, fox and dogs. Spurwinged lapwing select sanding, grassland, barren and field areas for nesting (Figure 7 and 8 a-d) .
