This is because you have the wrong return type. The delegate is of type List<Country> LoadChild(int id), but the delegate you try to convert it to is of type List<City> LoadChild(int id). That's the main problem, but it seems more architectural than syntactic. Either your delegate type is wrong, City does not inherit from Country, or City and Country don't implement a common interface. Personally, I wouldn't use a generic delegate at all; I'd go for something like this:
public delegate List<City> LoadCitiesDelegate(int countryId);

public class CountryDAO : BaseDAO<Country>
{
    public override Country Load(int id)
    {
        Country country = base.Load(id);

        if(country != null)
            country.LoadChild = loadCity;
        return country;
    }

    private List<City> LoadCities(int countryId)
    {
        CityDAO cDao = new CityDAO();

        return cDao.LoadList("CountryID=" + countryId.ToString());
    }
}

This probably wouldn't compile, but it's a general idea of the way I would personally do it

Between the idea
And the reality
Between the motion
And the act
Falls the Shadow
