The behaviour of foraging hummingbirds can be accounted for by assuming the maximisation of net rate. The currency, net energy per unit volume consumed suggested by Montgomerie et al. (1984), is shown to be an unnecessary means of interpreting behaviour when compared alongside an extended net rate model. The reason for the failure of previous net rate models to account for observed hummingbird feeding times lies in their negleet of the associated costs outside of the foraging period.
觅食的蜂鸟的行为可以通过假设净速率最大化来解释。蒙哥马利等人（1984年）提出的单位消耗体积的净能量这一衡量标准，与扩展净速率模型相比，被证明是一种不必要的行为解释方式。先前的净速率模型未能解释观察到的蜂鸟进食时间的原因在于它们忽视了觅食期之外的相关成本。
