羅伯特·里奇韋時常為他自己和其他人的書提供全彩色插圖,並在1870年代後期他的藝術水平達到了頂峰。儘管某些與他的同時代人可能已經製作了更具藝術感的效果圖,如丹尼爾·吉勞德·埃利奧特(英语:Daniel Giraud Elliot)(Daniel Giraud Elliot),但羅伯特·里奇韋的效果圖是最準確的,他的傳記作者丹尼爾路易斯(Daniel Lewis)曾對羅伯特·里奇韋形容“里奇韋可能是這個國家最了解鳥類顏色的人(Ridgway may have had the best grasp of bird coloration in the country)”。[65]隨著1887年《北美鳥類手冊(A Manual of North American Birds)》的出版,將羅伯特·里奇韋對北美鳥類的了解濃縮成相精簡的642頁和464張輪廓圖,並且作為當時成功的野外圖鑑原型,更於1896 年出版了第二版,蒙塔古·張伯倫(英语:Montague Chamberlain)(Montague Chamberlain)將其描述為“我們為工作的博物學家提供最好的東西(far away the best thing we have for the working naturalist.)”。[66]然而它笨重的體積對於野外使用來說是不方便的,它主要作為手邊鳥類特徵的生物檢索表而不是作為田野標記(英语:Field mark)使用。[67]哈利·邱奇·奧伯霍爾瑟(英语:Harry C. Oberholser)(Harry Church Oberholser)將插圖的品質描述為“在“美感”和“準確性”方面很少能媲美且永不被超越(rarely equaled, never excelled in beauty and accuracy.)”。[68]
