Since many of them strongly depends on nector, they are often nomadic. For example, Black Honeyeater sometimes occurs with over 100 in mallee scrub during flower season of eudcalyptus while there is none in other seasons. Size of honeyeater is very varied from tiny Rufous-banded Honeyeater (approx. 10 cm) to small crow size Yellow Wattlebird (approx. 45 cm).

While most of them are less colourful, they are often overlooked. However, I suggest to spend some time to observe this interesting bird group in Australia. There are probably many interesting discoveries for you.
