Kur ligzdo kaijas? Taču ne jau pludmalē? Vai tiešām kaijas ligzdo tikai uz Rīgas māju jumtiem? Kur viņas ligzdotu, ja māju nebūtu? Vai tad kaiju būtu mazāk? Vai var teikt, ka cilvēki palīdz kaijām?

    Ligzdas – dažādu augu daļu pasekls krāvums –, parasti, kaijām ir uz zemes. Dažādas kaiju sugas izvēlas dažādas ligzdošanas vietas:
    • Melnspārnu kaija ligzdo jūras piekrastē uz lieliem akmeņiem;
    • Sudrabkaija – seklos ezeros, zivju dīķos, purva ezeriņos uz saliņām, reizēm arī pilsētās uz ēku jumtiem, būvkonstrukcijām;
    • Kajaks – uz saliņām (parasti uz zemes, retāk kokos), pilsētās uz ēku jumtiem;
    • Lielais ķīris – ūdensaugu slīkšņās vai uz salām;
    • Mazais ķīris – dažādās seklās ūdenstilpēs.

    Kā redzi, māju jumti nebūt nav tās iecienītākās ligzdošanas vietas. Cilvēku �„palīdzība” kaijām izpaužas citā jomā. Tā kā kaijas ir iemanījušās izmantot pārtikas atkritumus, tad izgāztuves un konteineri nodrošina kaijas ar papildus barību.

    Pilsētās mājo arī citi ūdens putni, tai skaitā, upes zīrīņi, kuru kolonija daudzus gadus apdzīvoja preses nama jumtu. Diez vai par palīdzību var nosaukt zīriņa dabīgās ligzdošanas vietas – oļainas pludmales Daugavas krastos – izpostīšanu. Uz preses nama jumta zīriņi apmetās tādēļ, ka tiem vairs nebija citur kur dzīvot.
