Photographing birds in the wild is quite difficult. You need long telephoto lens often even two or three, without the tripod photos will be usually moved . Every species have very own habits and have favorite places where they can to find a feed and water. There are sometimes luck events when can take a good photo from freehand.
Macrophoto need other equipment, other lens, the tripod is necessary, very often speedlight very help to get perfect result. For taking photos butterflies also should to know habits of species. Early summer mornings are very good for taking of photos butterflies because insects perch on plants and often are covered a dew-drops.
I think that the flowers are favorite theme many photographers. When you see a very beautiful flower and take shot of it then appear photo isn’t so good as you expected. For taking good photos the flowers and other plants need many attempts.The landscape isn’t move and can think that is easy take it. No every view is interesting therefore maybe you will be need to choose only part of it. Good time for taking photos of landscapes are mornings and sunsets when light is the best especially in summer time because in midday light is to hard and shadows are hardly visible
