the effect of climate change on the karakoc creek wetland. Before August August 2021, I observed that birds that were never seen in August and that I rarely observed in August rarely did not arrive in 2021.2022.2023.I have determined that the migration dates of the bird species observed in the wetland have changed due to the change in air temperature. Bird species and names whose migration dates have changed due to climate change. Acrocephalus arundinaceus,Locustella luscinioides,Acrocephalus palustris ,Acrocephalus scirpaceus,Acrocephalus schoenobaenus,Pluvialis squatarola   I detected and observed that the birds that arrived at the wetland a month ago arrived a month later, the birds that arrived a week ago arrived one and two weeks later, the birds that arrived a week later arrived one and two weeks ago.
